"Each program button must have a unique button assignment."

[IT_Architect]

Whenever I go to Settings>All Settings>Personal>Buttons, I get locked into Buttons with the error message "Each program button must have a unique button assignment." Multiple buttons say <context menu> as I recall. I did some Goggling and reading, and some have had to do hard resets because they messed around in there and couldn't get back to where they were. My phone works fine, but I was wondering if there is a right and safe" way to get rid of this error. I'm running CHT and voice command. I see one of the keys was assigned to voice.

Thanks!
