[HELP] Armor porting texture issue

[N.Gamma]

Hello,
I am currently working on porting an armor from Skyrim LE to SE.

The esp and bodyslides have not been a problem so far, but I have encountered a textur error that I don't know how to fix.

The armor has only one mesh, but several color variations.

 

The normal version of the chest armor looks like this:

 

 

 

If I put on a different color variant of the chest armor, it looks like this:

 

 

To me, it looks like the texture of the rest of the armor parts is somehow loaded on the skin.

 

 

Can anyone tell me what the problem is and explain how to fix it?
