Try saving the controls to a file, then check it's correct with notepad and save with a different file name. Restart the game and load the new file into the controls menu.

I had a similar problem when adjusting stick sensitivity. I made a change, found I'd made a mistake and changed it back, but it was stuck with the bum setting. The above fixed it for me.
