sims 4 buggy custom content

Hi there, ever since the last update a few of my custom content hairs have become buggy? Well I don't know if this is the right word, but in CAS and in the game the hair looks like it has holes in it and even some new hairs I got were like this. Since some of the haircuts are my favorites, could you tell me if this is the update doing this or is it something else and what could I do in order to make it look like it did before?

There's also a picture for an axample of one of these haircuts.
