Unsolved Stamped-looking words on a skin

If you look closely, there are some words that are on the skin that aren't supposed to be there. Does anyone know what causes this?

This skin is private btw

 

That's an issue with the normal maps caused by the materials of your skin. Make sure you are using an up to date materials file for the pessima.

 

Ok thanks

 

Can anyone help me out? I'm having the same issue with the D-series and changing the file format won't do anything.

If you use this materials file for the pickup, the issue should be gone
