Here is a link to the wimdow frame.
I would suspect the reflectix would be what caused the warpage as others have mention the same issues with other windows.
The repair should be pretty straight forward. ( have someone on one side of door during removal and install to catch window)
You will need to remove the glass from the interior and exterior trim "clam shell" and remove all the butyl tape residue form the door. (Acetone)
Dry fit the new trim and glass to see if double layer of tape is required.
Apply new butyl tape to both pieces of window trim.
Install one side, glass, and the the other side. Tighten just far enough to start the tape ooze out the edges. Let sit for a bit and tighten the screws to get a little more ooze and frame appears tight. Do not over tighten and crack the plastic frames.
Keep us posted.
