Pro 9.0.13: other language than english shows blank page

Hi,
I just startet to upgrade our pro cluster on Centos from 9.0.8 to 9.0.13. The default language of the users switched to english. When a user tries to change the language from the settings menu, a blank page appears. I this a know bug?

Thanks,
Dirk
