Description jaguar_24112025 2025-06-27 13:01:49 UTC 
SUMMARY
This occurs in the 'Configure Extra Mouse Buttons' in System Settings under Mouse & Touchpad > Mouse in the top-right corner.
I recently removed my changes then tried adding them again and could not do so. 

STEPS TO REPRODUCE
1. Add changes to extra mouse buttons
2. Remove changes
3. Try adding them again

OBSERVED RESULT
The buttons no longer register in the dialog, instead they click as normal with their normal configurations.

EXPECTED RESULT
The buttons should have their normal functionality disabled while inputting them as a choice for a new mouse button binding.
