[Substance Painter] All blending modes function as an add, even when set to something else

[Michelle22466592ovzn]

As the title says, I'm having an issue when switching blending types. I've got an edge wear effect going and I'm trying to multiply the curvature by a paint so I can paint it on, however, I can see the paint layer when I paint, AND I can see the edge wear everywhere. I've got the edge wear set to multiply. Same story with a layer of scratches, except I have it set to overlay.
