B+ motorhomes

I haven't really had a chance to look over the newer models of the B+, but I think a lot of us probably have the same vinyl covered walls. Covering each seam in my bed and bathroom area is a matching self stick tape. Well, the tape now has started to wrinkle and bubble and I can't seem to find anything to stick it back down. Tried everything from plain white glue to liquid nails. Has anyone else had this problem? Looking for a fix other than trying to order new tape.

Thanks
