Epic Games [resolved] Dlc "downloaded" But Still Not Unlocked Ingame

Hello everyone,
I just bought the Nürnberg-Regensburg DLC and downloaded it. The Epic Game Store says that the DLC should have ~8GB, but it is only downloading aroung 350MB. And of course, the DLC isn´t unlocked ingame. What could be the error behind that? I already deinstalled and reinstalled multiple DLC to "force" the download of the full Nürnberg-Regensburg DLC. I also already verified the Game with the verify-function in the Epic Games Store. And yes, I also have lots of space left in my computer.
Thanks for your help

 

I forgot to mention, that the library says, that the dlc is fully downloaded
