Legionaries faces graphical issue

[Preussen Gloria]

I came here to ask a help or even just a suggestion from you guys,so i noticed just today when i was zooming close to the roman units that the legionaries,all of them have a very strange bug,their faces are all the same and they have strange small eyes,something that i never had before,i wasn't sure if this is due to the last patch or some graphical mods that i installed before,so i decided to make a brand new install of the game to my computer removing every previous file,and started again the game just with the vanilla version,but sadly i noticed that the problem is still there,i have a bunch of clones with small weird eyes,i wonder if any of you experienced such kind of problem,and if you could give me any other advice to fix the problem,here is a photo of my strange legionaries.
p.s
i forogot to mention that i run the game on ultra setting,i also tried any kind of graphical configuration but it didn't help for sure.
