Replying to Marker Jester/Griffon Toe Piece?

I have both jesters and griffons with the same problem so I was wondering if anyone had a solution or answer. Both bindings are mounted properly by a shop etc. but the toe piece that sits on the secure mounting plate has a TON of movement and play to it. The toe piece seems very loose, but both I and the shop could not find / locate any screw or point to tighten the piece on. Its kind of strange being clicked in but having my toe piece play a few mm each way. Im sure im not the only one to have this problem since it has happened on both pairs of mine.

Any help?
