Most of the screens just were not snapped into place correctly. I will say that the screens are a pain to get snapped in all the way. Some of them I thought were going to break the clips, but they finally all snapped into place. I found that I as having to push rather hard so the metal clip/spring would finally snap into place. I would get the top ones to all clip, then I would push the screen all the way up and then start clipping the rest in place.
