StreamDeck "Now Playing Widget" not seeing Button Up actions.

Mac Sequoia / StreamDeck PlugIn mode

When I use the StreamDeck "Now Playing Widget" to make a new BTT StreamDeck button, it is not registering anything from "Actions Executed on Button Up".

It calls actions if I put them in the "Actions Executed on Button Down" or "Actions Executed on Long Press".

This happens whether I have the "Cancel Button Up if..." box on or off. It's just not calling anything from a Button Up.
