Some cc not showing in game after the latest update (July 2018)

Hi, so I am having trouble with some of my cc after the latest update (July 2018). All my cc is still in the mods folder (no zip or sub folders), but after the latest update some of them just don't show up in game. (I activate the cc and mods in the games option after the update and I also tried removing the filter for feminine/masculine, did not find them) I did not remove the mods folder for the update (did not know back then that that can cause issues).

Mods are all fine, updated the ones that needed to be, just cc affected.

Also tried fixing them with the newest version of sims 4 studio, did not work.

I read somewhere you should delete the cc that is not working and download them again, but as a lot of cc is affected by this it would be a very time consuming solution, and I am not even sure if that would fix the issue.

Does anyone know if this work or a better way of fixing this problem?
