CBBE Body BBP Strange glitch/misproportion

[YiffMeister]

So I have this little issue with CBBE:

 

 

 

(Note: Vagina)

So, at the hips there is like this... I don't know what to call it but a glitch having to do with the mesh. I used bodyslide with advanced sliders to create this BBP body. Now, I don't think this happens with bodies created using only the basic Bodyslide sliders, but it's happening to me in this body. I also use XMPSE as a skeleton for animations.

I don't seem to find any sort of help in the FAQ over in the official CBBE download page, so I'm dropping this here in case anybody could be of help, which would be very appreciated. Not exactly a game breaking bug, but when you have Sexlab Framework installed, it's a bit annoying to see that popping up during animations.
