Very weird gmod problem

all the sweps I have downloaded so far like shotguns, now can’t reload. Normal reloads work, but the single shot at a time reloads don’t work at all for some reason. Also, when I scope in with weapons, they don’t actually scope in. All the do is bring the scope up to my face and be useless. Any suggestions? I know the SWEPS im using actually works, but what might’ve caused this?
