Cats stop using one of their bowls and now both only eat from one

Hi everyone, I have two cats. Noodle is about a year old and phantom is about 4 months old. We have automatic feeders for both of them and they get feed dry food In the morning. We also give them half a can of wet in the morning and at night. Since getting the cats they will snack from each others feeder but will mainly stick to their own feeder. One is in the living room and one is in our bedroom and they have full access to them all day. We have noticed recently that they seem to have abandoned the feeder in the living room and now both are eating out of the one feeder in the bedroom. Any advice on how to fix this?
