We had the same problem with our 2018. The seals don't have enough grip to stay on the glass without adhesive. Used rubbing alcohol to clean up the glass edges and seal grooves, then a thin bead of clear silicone sealer into the seal groove. Hardest part is figuring out the right/left, top/bottom orientation since the mating edges are beveled to make a good seal. No further problems this past year after doing what the installer should have done.
