MCX Stock Adapter QD Cup Non Rotation Limited?

I have an MCX stock adapter where the QD cup appears to be inserted backwards? There are teeth in the QD cup that would limit the rotation, however they are about 0.26 deep, where QD bearings are only 0.08 deep. Does anyone else have an MCX stock adapter that is like this? If this is on purpose, does anyone know what in the world this is compatible with?

There is a bit of a hitch getting the QD socket to accept the device, but when it gets in, there is free rotation. I have to press the button and wiggle it to get it fully inserted.

I have two stock adapters. One original without the QD and one with.

The one I have with the QD is as you describe. A real pain.

Plus I wish they were rotation limited.

Indeed it is really annoying. And you can see the cup has the teeth for limiting rotation, but they are set way too deep. What is hard to tell in that picture is the steel insert stops just after the teeth which is why I believe it is inserted backwards.
