Do you not have the aluminum railing along the top half of the door? That is super critical to holding the door seal. Only the lower half of the seal gets glued, the top half is wedged into the aluminum frame. If you don't have the aluminum frame, you need to get it and pop rivet it into place. The door seal will never stay in place without the frame. The gasket doesn't even have a flat surface for glueing at the top half since its made to wedge into the frame.
