Thanks, I have already read that topic, but there is no solution for the problem.
On the lid side there are 4 holes as mentioned the above topic:
"one hole on each side is a perfect circle and the other is elongated"
So it cannot be adjusted here.
The other side the bolts come from inside the cabin, I don't think it can be adjust there. It would require to disassemble the whole backseat part of the car.
