Slide Room seal drops when room is extended out

I hope someone my have a suggestion for solving a problem I'm having with one of the seals on the bedroom slide out on my Greystone 29MK. When the slide out is extended, one of the round-shaped, outer seals (not the flap that rests against the side of the slide out) slips within the mounting track that's attached to the side of the 5th wheel. This is one of the verticle seals that is compressed between the slide out and the 5th wheel when the slide out is retracted. The seal is pinched firmly in place when the room is retracted against the 5th wheel, but everytime we open the slide out, the seal slips down until the loose end rests upon the ground.

I don't know if I should glue the seal in place or if there is a better way to affix the seal to prevent it from dropping out of its retainer. Thanks in advance for any suggestions you can provide.

If you look closely near the top of that slide seal you should where a screw should have been holding that seal up in place.
Sometimes the screw was tightned a little too much and penetrated the rubber.
Just remount the screw in a different position,

Thank you for the suggestion. I'll give that a try.
