Assignments not unlocking after completion

I got the game on day one. After some time the assignments were made easier with smaller goals to reach. That caused problems with multiple assignments I was working on such as Rapid Fire and Conquest Challenge. I've completed both and I don't get the items unlocked. It's been multiple days. I tried restarting the game, restarting the pc, playing multiple games to the end, doing the assignments again. Im on Steam and also verified my files. Nothing helps. Nothing.
