Troubleshooting Player Hand

I am currently working on an update to the Strike of the Eagle module I recently uploaded. I wanted to include a button to count cards in hand (Polish North, Polish South, Soviet North, Soviet South), but in doing so I did something that screwed up the Player Hand. It now displays as a blank white window. It used to have a background graphic and an At Start Stack with a single “bluff card.”

I compared my current working copy of the module with the one posted above (with the “unbroken” player hand windows). I’ve checked the prototypes, spelling/capitalization, and have even deleted and recreated one of the player hands but haven’t had any luck. Any suggestions on how to approach this problem or advise on working with the Player Hand window?
