Require 2 finger swipes to swipe to very edge of screen before triggering

Describe the bug
Option doesn't work. When enabled, I can't get 2 finger swipes to trigger. 2F L/R swipes work 1 out of 10 times, while 2F U/D swipes do not work at all. I've even tried swiping my fingers from one end of the trackpad all the way to the other end but I can't get it to work.

**Affected input device
Macbook Touchpad
