Assembly issue

Good afternoon.
I am trying to work with a simple assembly. Pallets are fed on one conveyor, and boxes on another. We assemble the boxes on the pallet as specified in the Full Pallet assembly. For some reason, the robot places the first box on the pallet differently from the template, but after that, everything is correct.
Could you please tell me what my mistake is? Where does this first box come from?
Thank you!

I don’t know if you noticed that the second assembly step also has a placement setting (the little yellow square)


Just delete it.

Thank you so much to both of you guys!
