Ok I noticed this yesterday playing with mine. The adjustment screw is cheap plastic. I wanted them as high as possible. Screwing out will move them up but I turned it too far and the plastic screw popped out. The end of the screw has a ball shape to it that fits into the housing that must have socket hole. To reseat it I had to screw it all the way in till it pops back in. Then screw it out but not too far or the ball will pop out again. Hope this helps.
