WOD models won't work

Hello, I took a break from wow for a time and I had to delete WOW client from pc, yesterday when I downloaded the client again (not the OLD one) ..seems like WOD / Legion models won't work and it still runs the classic character/ npc models. Does someone know why this happend? Also, tried to download it multiple times, even tried both versions to check if I did not download the wrong one but still... won't work.

Please help me out..if anyone knows what's up.

It appears they were purposely removed, maybe for an update?
