My new unit card won't light up

[Ambigatos]

I edited a unit card in gimp for a new modded unit that I'm working on. Everything looks good and the card and unit look good in game, except for one detail. When I click on the unit card when on the battlefield or selection screen, it doesn't light up yellow like the other ones. I'd like to release the mod to the public, but not until I get this straightened out. Any ideas what caused this or how to fix it? Much appreciated.

fixed. Was a novice mistake in gimp with transparency
