LB RB indicators in UI?

- This is with a PC / mouse configuration, and I've never had a controller connected.
I had some glitch that messed up my UI (disappeared some bars, minimap gone, lost mouse control of ground targeting, etc. I got most of it fixed, but I still have these little LB and RB markers on various UI windows: Anyone know how to turn them off?

EDIT: Thought I found it. System Configuration, Gamepad settings, Enable Gamepad was on. Turned it off, still have LB/RB labels.
Edit 2: Defaulted all my settings. It turned on gamepad mode again, turned it off, still have the LB RB labels.

FIXED: Restored from a PC backup I fortunately made on 9/30.
