Could be the air pressure created from shutting the refer door is popping open the other one. There are are channels between the two so cool air from the freezer gets to the refer compartment. Try this as a test... s l o w l y close the refer door and see if that keeps the other door from popping open. If that works then it's likely an air channel is frozen up somewhere and you may need to turn the unit off for a day or so to let it thaw out. Moisture from leaking door seals, or doors that were left slightly open overnight can be sucked in and freeze up the air channels. I don't know if you are sort of slamming the door shut or not but the doors need to be shut slowly due to how air tight the new refers are.

check shelving and stock in door not stopping door closing. Check hinges tight and complete (sometimes have a self limitting plastic stopper that breaks, allowing weight of door to pull itself open)
