I had same thing first time I closed the canopy after placing that seal. I tried tucking it in as I was closing the canopy, had a friend with a plastic squeegee-type thing push it an as we closed canopy. After sitting closed for a while, It seems to remain where it needs to now. Will keep an eye on it, but it seems to work fine for now.
