I recently purchased a 2013 redwood which has the double roller shades black ones in back and the beige's shade in front. When I look at the shades it seems that the front Beige's shade unrolls from the back of the roller and the black one from the front of the roller. Thus when you pull the back black shade it causes the front Beige's shade to move also. It seems to me that both shades should unroll from the back. Are my shads put on wrong?? Does any else have this problem
