when i try to close my slides 1 & 2 they stick at the top and the bottom comes in at a distressing angle. I then have to grab the top of the trim and pull with my full weight to have it come unstuck. Once it is unstuck it proceeds to come in fine. Is there something i need to put on the seal to have it not stick or is this an adjustment on the bottom that is loose and needs tightening. I have a Reflection 337. Any asisstance to this problem would be appreciated.
