Localization doesn't work for DataTables?!

I’m using the Localization Dashboard to translate my game. However, while in general Text is translated, all Text inside DataTables will not get translated, no matter what!

Of course i compile the localization file.
I use StandaloneGame with “-culture=de_de” for german translation.

See pictures for more info.
