Terrible textures on "old" skins in the new warezone!

I recently bought a new bundle for the operator Bailey from bo6 and warezone. In case anyone is interested, the skin that is in the bundle is called Smoking Gun. The skin was unfortunately bugged as soon as I got it(it was fine in bo6, but now the textures don't load in properly). I must add that I am running the best possible settings for graphics and performance on a series x, with on demand texture streaming. Can anyone releate or give me a explanation? It seems like a lot of the older skins were integrated poorly in the new wz.
