That is what is showing in picture #1. 1/8" to 1/4" overlap at every joint. IMO you should not have to pry anything around to make it fit. The high spot came from prying to lay flat the one joint that over lapped when the rubbers were in place and it not very noticable in picture #3 but that spot didn't compress the rubber as well.
