Language Settings

Hey, I'm doing a course for german speakers - I already changed the settings go german in my account as well as in the settings/labels when creating new courses.

Unfortunately some sentences that I can't change to german manually stay in english. As for example when doing a knowledge check and the participant answers the question correct it automatically says "correct" and "try again" even though I would prefer this to be in german...

Any idea what's the problem here?:)

Best,
