What are these?

Could someone tell me where these should be?
Found them after service visit but can’t get any answer from Tesla.

Location right side behind seat, backseat floor.

Seems that those are on place. Very weird since they said that they didn’t made anything.

Technician checked all the bolts for loosening and did not find any loose bolts, all in torque. Technician compared the seats to several model 3 seats and the small spaciousness in the tracks is same in every car.
