Borderlands 3 (Xbox) Set language synchronization in German, how?

Moin, I wanted to ask how I put the synchronization on the Xbox One in German. The intro is in German, but the voice output of the npcs, etc. In English and with a German subtitle. I don't find a language setting in the settings.

Did you set your Xbox language to English? Believe that was dependent on it.

No, it is in German. Never had such a problem.

Usually change to "Language & Location". The game must be restarted for this. But if you haven't changed anything, that's pretty strange. 😅
