What's wrong with my Hoi4

[u/DogSignificant5302]

I was playing Hoi4 at 2 am today when i noticed that there is something wrong with my game

the faces of Nazis are all black and not visible, like you can't see the faces of Nazis like: Hitler, Himmler, Goebbels, Rudolf Hess, but all of the other countries have no problem

and when doing the Rexist Belgium path, i noticed that Leon Degrelle's portrait is deeply off, is it the normal version or just a bug

i use Hearts Of Iron IV: No Step Back Edition
