Background import issue

Hey, so I was just about ready to start animating a project today (using Harmony Advanced) but something weird keeps happening to my Photoshop background every time I try importing it into my scene. The background comes out entirely black, as in, a literal black rectangle, and I can’t figure out how to get it to import normally after several attempts of diddling around with the import settings.

Am I missing an obvious step or is there a problem with the Photoshop file?

Any help would be appreciated.
