"Double" body bug with CBBE outfit?

[Meety]

Hello, I have a rather annoying issue regarding bodybuilding/slider. Not sure how to even begin to describe it so I'll try my best. I'll start from the beginning, so I decided to install Modern Firearms mod from the author's website and along with the MF came with an armor accessories package called "CUTE" (Made by the same person I believe.). Unfortunately it did not come with bodyslide files so I took it upon myself to mold and try to mess around in the studio to make it fit, I managed to make some pieces fit.

 

Now here's the issue, I somehow managed to make it fit to a specific preset I preferred and it worked mostly in-game (minor clipping issues were expected). Now I managed to find a new body preset off the Nexus I wanted to use, so I downloaded it and did the usual batch build to all of my armors, it worked for most pieces except for a few. These pieces (The leg armors, black color for both left and right legs - Only those.) for some reason I can't find out why it's still showing the old body rather than the newly built one I just used to create a batch build with. So now when I equip those pieces specifically it shows both the old and the new one. When I remove said pieces, everything returns back to normal (Basically it shows the new body I built.)

 

I've attached a screenshot depicting my issue, like I said this is the best I can explain it. The set of 'lower' breasts are the old ones I was using and the 'upper' ones are the new ones I just built.
