Highlight appearing on decal

I’m currently making a stylized cartoony game, and using a part for the face to have more expression on a character. I’m having issues with this as the highlight in the model is going over the decal, and it isn’t the part the decal is on as it doesn’t appear from the back and the part is as thick as the head.

You either have a backround or border, set bordertransparency to 1 and backround transparency to 1
