Since the 124 uses rubber all the way around the sr opening, you first need to determine if the seal is or is not seated completely. I would first spray Windex or sylicone spray on the entire seal and see if this helps the closing of the panel. If it still doesn't close, then the problem has to be the seal not seating completely. You should be able to feel any bad seating by running your finger around the entire length of the seal.
