EXP Pedal is switching Preset Bank if pressed down hard enough. How do I change this?

If I push down the EXP pedal to 0, my patch bank switches to the next bank. How do I change this?

Impossible on a properly functioning unit.

Return it.

*Update* 

 

I don't believe it's the actual EXP controller that is the culprit. It seems to be the preset's UP foot switch itself. It's very finicky. Contact with any footswitch or the EXP pedal is causing it to get stuck cycling through presets. The only fix i've tried so far that seems to work is to twist the UP switch counter-clockwise a few turns. This stops it from randomly cycling through the preset bank and allows me to choose a preset.

I don't even understand what you just said.

So I took the back cover off and hit the switches with Deoxit and sprayed the inside with compressed air because it was a little dusty. That seems to have fixed the good majority of the problems I was having. The only small issue I have now is if I hit the Preset Bank Up switch without clicking on a preset (flashing) and I hit the EXP pedal kind of hard, it will go up to the next bank. I don't foresee this being a issue on stage so I'm not overly concerned. The past month I have been leaving the unit out of it's case and on the floor. I guess it must have gathered some dust. I will lay a small towel over it when it's not in use going forward.
