I did try a different texture and had the same issue. I don't know enough about shaders to experiment with that. Like, I don't know if the shader can be replaced with another one or if it has settings, and don't know where to find the shader or settings. I did find a setting for displacement and it just had a question map by it with apparently no displacement map. The good news is after starting over and rebuilding the character from the default Victoria 4, the rebuilt character doesn't have this issue. So I thank you both for trying to help me, and one way or another the problem was solved. I just may never know what went wrong...
