The front panel is the one that is driven by the rear motor. The trailing panel is hooked to the front one via 2 small tabs that are attached to the "vent screen"

Perhaps the pieces that you see which are broken are these tabs? This is also why you are able to slide the rear panel on it's own - it's not connected to anything in terms of be driven forward or reverse.

The panels themselves are actually the same size, but only the front one is driven by the "headliner lock mechanism" and the rear panel is drug along by the tabs in the pictures above. this mechanism is also what the vent mesh panel locks into. As the panels are split apart when it vents, the small tab remains in the channel on the rear panel - and the pulley system allows the panels to split to show the vent mesh.

The channels that the vent screen slide into are located at the very end of the cassette. The front screen would have to be manually cranked to the rear (this would be the rear motor, the one located under the "bump" in the headliner panel in front of the hatchback), and there is also this "stop" piece that would have to be removed before it you could re-install/repair the vent screen piece.

I don't see anyway around having to remove the sunroof cassette to be able to repair this. Because the fact that the front panel isn't moving is to be expected - the motor would have to run for that panel to move.
