How are dual shades installed/removed? My 310RL has sun shades and black out shades installed and I have difficulties with two of the shades, rarely using them because I can't get them to retract. It appears they are clipped in place at each end of the shade, but I don't want to force the bracket open and risk bending the bracket.
Figured it out, the L-brackets are a little more difficult to see with dual shades, and the valence under the rear cabinets is mounted directly to the cabinet - no L-brackets.
