empty categories in german translation

When browsing available apps by category, some category lists remain empty although there are apps of this category. So I can only use the special category "all" to browse apps, which is not really nice. Affected are:

"Kinder" "Entwicklung" (english name is development, I have installed apps from this category) "Spiele" "Büro" (english name is office, I have installed apps from this category) "Wird gelesen" (english name is reading, I have installed apps from this category) "Sicherheit" "Hintergrundbild"

It seems that apart from the first three special categories (recently updated, new, all) all those where the translated name differs from the english one are empty.
