Modifier Keys Dont Work With Conditional Activation Groups

Describe the bug
I can map the Caps Lock key as a Key Sequence to trigger any other action in Global/App Settings. However, in a Conditional Activation Group I dont seem to be able to map/capture a "bare" modifier key as a Key Sequence unless it is also accompanied by a normal key press (e.g. "Cmd E")

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Macbook Keyboard
