Center seat runners

Anybody got issues with the middle row center seat runners?
Had the seats out at the weekend for a good hover and noticed the plastic trim round the runners was unclipped and distorted. Spent ages getting them fixed back correctly.
Then couldn't get the seat to clip back down.
The plastic trim around the center runners has raised edges (so is different to the other seat plastic trims) presumably to prevent the swopping of seats.
The only way to get the middle seat to clip down is to force the plastic to one side. As it has been since we got it.

Should fold down when you pull the lever on back of seat,if not cable probably snapped if so it comes as part of the seat back trim.If your talking about the getting the rear of the seat back down(after removing from its runners)I just slam the motherf**ker down as it has a habit of springing back up again
Personally I am sick of stripping these(and the others)down & rebuilding them & you are right about the center seat middle row.....try putting another seat in its place......took me half hour to get it out
