camber-caster

Hello. Tell me what to do. I bought a new Kia Cerato, about a week has passed, mileage is 450 km. The car pulls to the right, not strongly, but it doesn't depend on the road. I came to the dealership, they inspected it, did wheel alignment and said that the parameters were slightly off. They gave me a work order, which stated that the recommended repair is rear axle alignment, shifted to the left side. After leaving, nothing changed. Question: what does "rear axle alignment shifted to the left" mean? I can't imagine that. And most importantly, how will it affect the tires? What do you advise? Thanks.
