Yes this is it. This should have been detected by CATS.
Oh dear you will need to manually edit this if CATS can't detect it.

And it'll require a lot of time to guide you through it piece by piece. You may want to find someone in-game that will help you through it.
What you need to do here is pretty advanced stuff specially without the help of CATS.

I can do it but it'll take me a lot of time 6 hrs or so to fully guide you through what needs to be done. And I don't think I have that kind of time.
Commission a fix and without guiding, your model can be done in an hour or so by someone with experience.
