Disabling triggers doesn't work

Configuration Help & General Discussion

  1. In All Apps, create a trigger for my Corsair mouse -- button 3 triggers keyboard shortcut
  2. Disable the trigger I just made
  3. Create a different trigger -- button 3 triggers different keyboard shortcut
  4. If I click button 3, I get a contextual menu listing both actions

How do I actually disable a trigger?
