Wod models and non-english game

Hello,

Please forgive by advance my bad english.
I downloaded a french version of wotlk, and i wanted to play on your server, what i succesefully did. I also downloaded warlord of draenor models that your propose on your website, and the folder makes the game work with perfect models.
But what i can't do is to replace files containing the english version with files that contain the french version: textures are now a bit buggy (faces are not completely modeled, horns are green, and some other bugs). is there a solution to put the game in an other language than english with the wod mods ?

Regards,

LM
