Slideout top seal?

[normanoid]

I purchased an '04 Raptor 3512 with couch/dinette slideout. The seals on the top and sides are the same, an offset flap seal 1-1/2" or so tall. The side seals will flip in and out with the slide, but the top won't flip out with the slide. It touches the slide roof the whole width. Do I need to adjust the slideout up to put more pressure on the gasket to help flip it out? The rubber on all 3 sides seem to be soft and in good shape.
