2D Painting Issues

Hi everyone. Im pretty new to this. Ive been in substance painter before but I have only worked on hard surface stuff previously. I am working on my first ever character model that I made and I am running into an issue where I cant paint masks or anything in the 2D view for the body. Everything else works fine. Im attaching a short video to demonstrate what is going on. Maybe someone can help. I have baked a high poly mesh onto a low poly one if that helps.
