Trouble activating Panzer Expansion 3

I have the Panzer module installed (Panzer_1-6-8.vmod). I downloaded the expansion 3 module (PanzerExp3_1-1) and the associated map boards.

When I start the Panzer module, I find that the boards for expansion 3 are available, as are the American units, but the Panzer IVJ seems to be missing from the inventory. Any ideas where I can find this unit counter?

I’ve been trying to mark this issue solved but it appears I have no button options available that allow me to do that. Problem solved.
