Return loads track in performance mode

Hi,

I got an issue with "Return/Enter", which loads a selected track into deck 1 and I can't find a way around it. When I'm djing live and hit Enter to confirm something or just by accident, because its placed above shift - deck 1 loads an unwanted track.

Happened yesterday once and the crowd didn't like it.

How can I disable Return Hotkey in performance mode?
