Open XBox Guide with 8BitDo?

Suddenly, my 8BitDo Pro 2 Home Button no longer opens my Xbox guide.

I think it is still mapped properly in 8Bit Ultimate software, as the Home button (bottom right on controller in screenshot) is Mapped to the HOME icon (bottom right of screenshot):

Any help would be greatly appreciated!
