I could not complied your sample, ServiceParameterCollection was missing... so I have prepared you my working samle. Here we go...

First lets create config classes, take notice on AddItemName ConfigurationCollection parameter (I think this is what you are missing in your code):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;

namespace GP.Solutions.WF.DocumentProvider.Entities.SharePoint
{
    /// <summary>
    /// Base SharePoint 2010 provider contiguration
    /// </summary>
    [Serializable]
    public class SharePoint2010Settings : ConfigurationSection
    {
        /// <summary>
        /// DocumentStorageRoot
        /// </summary>
        [ConfigurationProperty("SiteUrl", IsRequired = true, DefaultValue = "")]
        public string SiteUrl
        {
            get { return (string)base["SiteUrl"]; }
            set { base["SiteUrl"] = value; }
        }

        /// <summary>
        /// TitleProperty
        /// </summary>
        [ConfigurationProperty("TitleProperty", IsRequired = true, DefaultValue = "Title")]
        public string TitleProperty
        {
            get { return (string)base["TitleProperty"]; }
            set { base["TitleProperty"] = value; }
        }

        /// <summary>
        /// ProvideFileAsLink
        /// </summary>
        [ConfigurationProperty("ProvideFileAsLink", IsRequired = true, DefaultValue = true)]
        public bool ProvideFileAsLink
        {
            get { return (bool)base["ProvideFileAsLink"]; }
            set { base["ProvideFileAsLink"] = value; }
        }

        /// <summary>
        /// DocumentCategories
        /// </summary>
        [ConfigurationProperty("DocumentCategories")]
        public SharePointDocumentCategoryCollection DocumentCategories
        {
            get { return (SharePointDocumentCategoryCollection)base["DocumentCategories"]; }
            set { base["DocumentCategories"] = value; }
        }

    }

    /// <summary>

    [ConfigurationCollection(typeof(SharePointDocumentCategory), AddItemName = "DocumentCategory", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class SharePointDocumentCategoryCollection : ConfigurationElementCollection
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new SharePointDocumentCategory();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((SharePointDocumentCategory)element).CategoryName;
        }
    }

    [Serializable]
    public class SharePointDocumentCategory: ConfigurationElement

        /// <summary>
        /// CategoryName
        /// </summary>
        [ConfigurationProperty("CategoryName", IsRequired = true, DefaultValue = "")]
        public string CategoryName
        {
            get { return (string)base["CategoryName"]; }
            set { base["CategoryName"] = value; }
        }

        /// <summary>

        [ConfigurationProperty("FolderName", IsRequired = true, DefaultValue = "")]

            set { base["FolderName"] = value; }
        }


        /// <summary>
        /// TitleProperty
        /// </summary>
        [ConfigurationProperty("OverwriteFiles", IsRequired = true, DefaultValue = true)]
        public bool OverwriteFiles
        {
            get { return (bool)base["OverwriteFiles"]; }
            set { base["OverwriteFiles"] = value; }
        }

        /// <summary>

        [ConfigurationProperty("CategoryFields")]
        public SharePointCategoryFieldsCollection CategoryFields
        {
            get { return (SharePointCategoryFieldsCollection)base["CategoryFields"]; }
            set { base["CategoryFields"] = value; }
        }

    }

    /// <summary>

    [ConfigurationCollection(typeof(SharePointDocumentCategory), AddItemName = "CategoryField", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class SharePointCategoryFieldsCollection : ConfigurationElementCollection
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new SharePointCategoryField();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((SharePointCategoryField)element).FieldName;
        }
    }

    /// <summary>
    /// Class that determines specific field
    /// </summary>

    public class SharePointCategoryField : ConfigurationElement

        [ConfigurationProperty("FieldName", IsRequired = true, DefaultValue = "")]
        public string FieldName
        {
            get { return (string)base["FieldName"]; }
            set { base["FieldName"] = value; }
        }
    }

}

And here is web.config part:

  <configSections>
    <sectionGroup name="CustomConfiguration">
      <section name="SharePoint2010Section" type="GP.Solutions.WF.DocumentProvider.Entities.SharePoint.SharePoint2010Settings,CustomConfiguration" allowDefinition="Everywhere" allowLocation="true"/>
    </sectionGroup>

  </configSections>

  <CustomConfiguration>

    <SharePoint2010Section SiteUrl="http://server" TitleProperty="Title" ProvideFileAsLink="false">
        <DocumentCategories>

          <DocumentCategory CategoryName="Vhodni računi" FolderName="" OverwriteFiles="true">
            <CategoryFields>
              <CategoryField FieldName="Datum" />
              <CategoryField FieldName="Vrednost" />
            </CategoryFields>
          </DocumentCategory>

          <DocumentCategory CategoryName="Zahtevek za dopust" FolderName="" OverwriteFiles="true">
            <CategoryFields>
              <CategoryField FieldName="Datum od" />
              <CategoryField FieldName="Datum do" />
            </CategoryFields>
          </DocumentCategory>

        </DocumentCategories>
    </SharePoint2010Section>
  </CustomConfiguration>
