Broken texture on the Zombine NPC.

I bought and downloaded Half-Life 2: Episode 2. After playing half of the game, I decided to look at all the stuff from it in garrysmod. However the Zombines textures are broken, yet everything else is normal. Does anyone know how to fix this? I also have no sounds for the zombine, besides the grenade ticking and explosion.
