Mermaid cc skin tones problem?

[Black_CHaos_]

So, I've got a problem. 

I wanted to create a sim, a mermaid to be specific..

I was trying to use my costum skin tones cuz I think they look better compared to the base game skin tones.

Anyway, I have the following problem : When I click on it, it's working fine, but then I go see the mermaid form and I don't know why, but the mermaid tails don't work right? They have the skin colour they got through the cc and I can see their genitals and their butt? 

I don't think thats intentional, cuz without the cc it works fine.

So, then I deleted all files I could find from wicked whims (I hope so atleast), but it's still not working right? 

I've tried to delete everything a few months ago too, the sims were still naked in cas and ingame when they peed n stuff. 

 

So my question is : Does anyone know, if there is a file I may have to delete so the whole mod is deleted which I may forgot (I don't want to use the mod anymore and it makes me kinda uncomfortable to see them naked always ngl)?

And why the mermaids tails look so awkward with specific costum content? (Some costum content works, but its not the one I want to use)
