Are you making the Bars in WED, if so try making them in med. (Just a thought) I am trying to make a prison level for my game to and i made the door in MED and imported it into WED and ran the level with no errors but When i went to the , the two bars on the outside (same size bars on the inside) were visible and the middle ones weren't. I just deleted them and thought of putting an image of a cell door there instead.
