Using merged dictionaries can get a bit tricky if you have dependencies between other merged dictionaries.

When you have multiple application-scope resources the order of the declare is important. They are resolved in the inverse order of the declare, so in your case you should have the order.

<Application.Resources>
<ResourceDictionary >
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="Styles1.xaml"/>
        <ResourceDictionary Source="Styles2.xaml"/>
        <ResourceDictionary Source="DefinedValues.xaml"/>

    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

Also, you may need to reference the other ResourceDictionary in Styles1.xaml. This worked for me in Styles1.xaml.

<ResourceDictionary "...">

  <ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="SharedValues.xaml" />
  </ResourceDictionary.MergedDictionaries>

  <Style x:Name="AnotherStyle"
         TargetType="Button">
    <Setter Property="Height"
            Value="{StaticResource SharedValue}" />
  </Style>
</ResourceDictionary>
