Steps to reproduce

I found in MaterialLocalizationDe a translation "TBD" and some clear translation errors like there is no ß in de-CH

Expected results

No TBD translations in German and no ß letters in de-CH.

Actual results

There is a translation "TBD" which seems to be wrong. I also found wrong translations for de-CH (basically de-DE just in upper case) and some clear translation errors like there is no ß in de-CH
