Update:
at my final conclusion to this season, I'm pretty sure, history didn't count the first game after update (or it's one behind... however), because: at history, Watzinger has most appearances, with 49. If you look at the screens, Fellinger has 50.
At my whole squad Watzinger and Fellinger played all games. There's the issue.
But this didn't solve the issue with the missing goals at line up.
