Can't make Human DK

Hello!

Sorry if I'am writning in wrong place.
I have a problem, I leveled my other account to 55lvl and now I want to create Human DK and there is error creating character. Somebody knows why?
I can make for example female human DK but cant male or can make male blood elf DK but can;t make female blood elf DK.
Why do I ahve this error?

Edit: It looks like some character looks are bugged and cannot be created I can't creat any class human with that look.
Edit 2: I think that there is a problem with some types of hairstyles and characters with those cannot be created.
Does someone knows how to fix this?

In the character selection screen, you're allowed to choose the hairstyles which are only available through the barber in game which is why you are getting the error. There is no fix, just go to the barber in game if you want those specific hairstyles.
