Indoor Plastic Trim

Hey guys, I know I've been gone from here for quite a while, and I'm sure you guys miss my dorky Iowa pictures, but I have a question this time. On the inside of my E, the plastic trim is starting to almost warp away from the frame and start to look ill-fitting. It's on the upper part next to the rear skylight. Mines an '04, and it dosen't seem this should be happening. Does anybody else have this issue??
