I wanted to assembly the freshly bought Playseat but I'm having an issue. I watched 4 videos on youtube and checked the manual 10 times, but I cannot get the backseat to fit properly, assuming that the position is correct in the below picture:

The pins do not fit into holes:

The only way it fits is in the below position but from what I can see in manual, in pictures and in videos, this is not how it should look:

Am I doing something wrong or did I get a faulty unit? I also saw some people having missing two screws, the small ones. Seems I don't have them as well. I have 10 smaller screws and 2 bigger ones.
