Framing question

On a new build home, pre-drywall, doesn’t the top plate of partition walls have to attach to the trusses? I see a consistent gap of about 1 inch between the top plate and the truss on most of the partition walls in this home. I can push on the walls and they move side to side at the top. The construction manager said this was correct. Can you advise? I’ve attached a couple of Photos.
