Mixed Language UI Rhino 7

We have the problem of different languages (German/English) in the user interface with our Rhino 7 installation.
Only the German language pack is installed. There are user profiles for each user on the server. If we delete the user profiles locally and on the server, the problem seems solved, but it reappears after some time. Does anyone have a solution or idea for this? Thanks to all

i saw some issues too though far less complex maybe, it does seem to be a crossplatform issue to some degree. my system language is set to german and some things were stuck in german, when Rhino was actually set to English. i assume it was taken care off at least from my point since i did not see this happening anymore or i am not aware.

one little left over which of course only relates to your problem peripherally please bear my amendment.
