Garry's Mod server NPC animations

I have had this server up for quite a while now and I haven’t been able to fix the Npc animations, I looked around and tried extracting the GCF’s into the server folders ( server/hl2, or server/orangebox/ ), but it seems like nothing works, so I thought I’d create a help thread
below are just some of the glitches that happen

I’m not sure what causes this, but it seems like a lot of people have this problem
