Need help with Alpha layers

Hello All,
I'm currently working on a simple Virginia and Truckee reskin of Smokebox's wonderful consolidation. I tried alpha-ing out the 0 digit "painted_and_stencilled_number_0.TgPcDx" so that I could have two digit numbered engines. However I can't seem to get it so that the blank numberboard background still shows up without the number. The two pictures show as I have it so far, the first as it looks on the cab, blank as it should be. The second, showing the numberboard, where the problem lies. Any help would be greatly appreciated.
