Yeah - there is the one under the thing that holds it in place - some times those come out - kind of a PITB to mess with - I had one came with a screw missing holds that thing in - got one off my donor machine to fix it. That retaining device needs to have a bit of a spring to it or it sure doesn't work. Some times they just get out of place - someone pulls it all the way out and then can't get it back together or whatever the genius did to it.
