Wrath of the Lich King WOD character models issue

Greetings, I am currently experiencing an issue with the WOD character models on the WOTLK warmane realm.
Warmane version: http://imgur.com/a/Y7C9l
Retail version:http://imgur.com/a/pHPkG

As you can see in the comparison the warmane version for me are pretty weird compared to the retail version. Faces are weird, undead male jawless version is basically a missing texture. I'm not sure whether this is intended or it's just for me that's why I am creating this thread.

It's not still fully finished it will be updated with new realm Lordaeron.
