It will slide off, if you slide it forward, there is a plastic catch to keep it from coming clear off but if you put a bit of upward pressure at the rear of the toe it will just slide off. Make sure you've got the unlock lever all the way unlocked. Pry up between the track and the toe at the rear, crank the lever and push forward. Only takes three hands.
