After struggling with removing the RS center piece I figured out the easy way...Push the tab on the bottom, get your fingers under the top, front of the center piece and pull up on it.Use a screw driver to push in on the center piece in each one of the 4 slits. The corner will pop-out. Do each one at a time.
