Joe,
  It is a wear issue, and a tolerance issue. I had to re-file the
notches to better shape, and also disassemble the latch from the glass
to shim it up in the hole in the glass.
Disassembly is a trick. Small short screwdriver from underneath, pressed
up, while 1/4 turned with pliers many turns to release. (believe was
slotted, but may have been allen. Anyway, would be  better replaced with
allen.) Clean and lube before reassembly.
