Both my masters applications are faulty and I cant find a reason why

I applied for 2 masters application in Germany, one for Computer Science in Kiel, and another for AI in Cottsburg

Today I checked the applications and they're both marked faulty, with no reason given. What could be the reason?

Is it possible that I have a missing document

For context, here are my submitted documents (The titles are edited to remove my name)
