Strange behaviour in Keyboard language

Although i have a german system, the keyboard is US after everz new start. I have added German Germany and set this on the first place. US after new start! Added German and deleted US, US after new start!
Delete system and reinstall???
Any ideas?

I had the same problem with the GB keyboard, the solution was to remove the fcitx5 package.

Hello Richard,
that is indeed the solution! Thanks!
