Extensions loaded but counters from one only are visible

I have a simple question, but haven’t found an answer on the forums through searching. Perhaps you can help.

How do I make game piece palettes from multiple extensions visible within a module?

My goal is to group game pieces from each extension into a different tabbed panel. When I click on the game piece palette button in the main tool bar (labelled cards and counters), I expect to see options for choosing the game pieces from the appropriate extension.

Right now I only see one of the extensions’ cards and counters. The extensions’ game pieces are organized in 3 pull-down menus within a tabbed panel. I wonder if that’s my problem. I may need to set them up differently.

Both extensions were successfully loaded within my main module. There are no errors in the chat window.

Thank you for your help.
