Logic option+ functional buttons' shortcuts(key combination) could not trigger BTT kb shortcuts.

Hi, I am using the functional buttons of my logic MX Master 3 mouse.
Here is my question:
While my functional buttons are defined as key combinations, they couldn't trigger the BTT keyboard shortcuts.

Only when my functional buttons are defined as a single key, then it could works with the BTT keyboard shortcuts.

I'm not sure if this is a BTT problem.
But l am still looking forward to some solution.
Thanks!

Solved, updated logic option+.
