can't use 2 Finger taps: context menu displayed, even with BTT actions using the modifier key

concerns: 2 finger tap anywhere on the trackpad
I have been using BTT for years and have many trackpad triggers using 1,3,4 and 5 Finger Taps using different modifier key combinations.
I understand that the default 2 finger tap is the context menu and I want to leave it like that.
My problem is that whenever I want to create a BTT trigger using the 2 finger tap along with a modifier key, I still end up with the context menu.

I wonder if the Mac OS trackpad settings override all modifier keys, but I can't turn if off because I need it.

thanks in advance for your time and help
