Your problem seems to be in:

if(stundenContainer[j]!=null)
    Log.d("VplanWidgetViewsFactory", "stundenContainer["+j+"]:" + stundenContainer[j].toString());
else
    Log.d("VplanWidgetViewsFactory", "stundenContainer[" + j + "]:null");

if (stundenContainer[j] == null) {
    //Freistunde
    Log.d("VplanWidgetViewsFactory", "Freistunde");
    // HERE -----
    stunden.add(new RemoteViews(context.getPackageName(), R.layout.fragment_stunde_widget));
    faecher.add(new RemoteViews(context.getPackageName(), R.layout.fragment_fach));
    stunden.get(stunden.size() - 1).setTextViewText(R.id.textView_lesson_nr, "" + (j + 1) + ".");
 } else if (!stundenContainer[j].get(0).getSubject().equals("ignore")) {
     Log.d("VplanWidgetViewsFactory", "stundenContainer[j].get(0).getSubject(): " + stundenContainer[j].get(0).getSubject());
     // HERE -----
     stunden.add(new RemoteViews(context.getPackageName(), R.layout.fragment_stunde_widget));

You are adding it twice.. , but only when the first item is not ignored, so it appears random.

stunden.add(new RemoteViews(context.getPackageName(), R.layout.fragment_stunde_widget));
