Dometic 3-Button T-stat Issue

[BandBmalin]

I was solely in charge of getting the trailer ready to bring home after camping as my poor wife had to get up and leave for work at 5am. Normally, she handles the inside stuff and I, the outside. Well, short story is that I forgot to secure the bedroom door before I left (and I left the dog's retractable leash on the picnic table - but that's not important!) and when I got home, found the plastic cover with the buttons sitting on the floor in the bedroom. Apparently the door had slid and bumped the unit enough to knock the cover off. Everything looked fine so I snapped it back in place.

The problem is that as long as the cover is on, the "up" button seems to always be on. I look inside the cover and there is just foam for each button and I can touch each "pole" inside the thermostat and everything works without the cover on like it is supposed to. The only issue is that every time I snap the cover on, the "up" button is always depressed.

The cover is pristine with nothing showing pressed and there is no difference between any of the buttons on the cover such as the "up" button being pressed in or anything.

Thoughts???
