Maxis Match Hair glitch?

Hi, I've been experiencing this weird glitch in CAS with some hair cc. I noticed more often it's maxis match cc hairs that are affected. A green streak usually appears somewhere in the hair in random spots. The streaks show up in live mode too if I use a hair with that glitch. I don't know what the problem is. I thought it may have been the more columns mod, but I removed it from my cc and it's still there. Does anyone have any ideas on how to fix this? (PICS INCLUDED!)

My computer is an Asus PC

Don't know if it makes a difference but I run the game on an external hard drive
