It is obvious that the rubber needs to move towards the stainless part. Your finger should not be in that gap, the rubber needs to move to the left in that picture. It looks like there is a hole in the stainless trim and I can only assume there is a hole in the rubber and there should be a rubber rivet in the rubber and stainless to keep it from moving to the position it is in in the photo. I can't help you if you can't see it in person.
