Hello I don't know if you still have problems with your sliders but if so you can update them with the fixer by CmarNYC (same for Alpha hairs and skins)
The latest version of Sims 4 Studio, 3.1.5.9, has batch fixes for CC hairstyles and slider mods that were affected by the Werewolves patch. The new version has:
1. a batch fix that will repair these packages so the hair will look right and still be compatible with the color sliders.
2. a batch fix that will change hairs that aren’t compatible with the color sliders so they are.
3. a batch fix that will fix face and body slider mods so they work in patched games.
If anyone is still having problems with CC alpha hairstyle or slider mods, this is another option for your consideration.
