I have Painter X and I think I may have accidentally changed the settings on it somehow, but I'm not sure what I did. When I try to paint on areas of layers that I have not yet painted on, the strokes don't show up. However, when I paint on parts of the layers that I have already painted on, it does work. I can also paint directly on the canvas. It's not just on a specific file, it happens with every file I open now and all new files as well (meaning I obviously cannot use layers on new files). I've tried restarting the program and restarting my computer, but neither of these have worked.

Can anyone tell me what I did or how to fix this problem? Is there a way to reset all of the settings to factory default?
