Match by mesh name not working

[hechtCGI]

I just tried the match by mesh name option with a simple setup of high and low meshes in both painter and designer. It works flawlessly in designer but painter just gives me a black map. Since I'm using the exact same settings for both, I'm assuming it's a bug in painter.

These are the testmeshes, they are at the exact same position when exported. Just moved them here to show both meshes.
