Without seeing how they're designed and hung, I can only add what I did in the past. On my Monaco Diplomat, the doors did the same thing. The frames were basically coming loose. I had to remove the doors and then remove the frames and reattach them in the original position.
3M makes a double sided tape that comes with a liquid agent that cleans/preps the surface for a better connection....won't come apart. It's not an alcohol prep, it's a tube with a foam applicator tip that you wipe on the surface. I tried to find it on Amazon, but didn't see it. Maybe someone will remember the name.
