Today I noticed that one of my inside slide seals is coming loose. The channel it attaches to is missing a staple on the end and loose also. I will staple the channel back in place but have had no luck installing the seal. It looks like this
seal. I'm trying to snap it in place but it keeps coming undone further and further. Should I be able to snap it back on over the channel or will I need to remove the entire seal and slide it over the channel? The seal came loose after it stuck to the slide. I've treated the seals and they no longer stick.
