Rivets PTA Mask Not Working

Hi, I’m using the Rivets module and when you go to the record sheets and try to mask the PTA information, the header changes from white to black, but the mask image is not applied to the rest of the screen. I opened it in the editor and the mask image is there. Any thoughts?

I have found the error in the module. I tried contacting the original author, but got a bounce back from the email. I will upload the fixed mod (v1.2).
