Part of the inside came off, Is this important?

On my 2016 Classic this Summer, the rubber strip between the cedar closet and the kitchen came out of hiding. I tried to get it back in, but failed, and I finally cut it off because it was annoying my wife so much. From what I can see, it's cosmetic and not that important. Am I correct or wrong? I have attached a picture.

It’s a trim piece between the inside skin and wooden wall. Not structural but I would have probably loosed the cloest so that I could have slipped the trim back over the 3/4” plywood wall instead of cutting it off.
