Please help me to figure out why some of genitals just won't show up in WW body selector (non-default, not outdated, 1 folder depth).

[Gerfeniks]

As the title says i'm having an issue with WW not seeing some genitals. For example BTTB 6 male lover body is in the same folder with BTTB 6 upper body. Upper body is fine but lower won't show up. I can see them in CAS as a clothes, but not in WW body selector. I also have Simple Penis v2, it works fine on male characters but not in female(with penis) body selector. Do they conflict? They really shouldn't, because all of them are non-default.

Even Dumbaby female breasts have the same issue. There are 3 versions, but only v2 shows up in WW body selector. 

The folder is literally Electronic Arts/The Sims 4/Mods/"Name of the mod".

 

I have no clue what the problem might be, so i'd appreciate if anyone could help.
