thanks a lot for you responses! I indeed suspected that this might be the cause but when I remember correctly, it also shows for "in der Gegenwart" A2 as answers - which was never set by default and was never changed..
However, to answer your question why I didn't know: five people (also students) in total worked on this project, so I wasn't sure if someone changed it. And even if someone indeed changed it, they'd probably not admit it (but there's ofc also the chance that I did it and don't remember).
Anyway, thanks for your help and support, really appreciate it
