There are lots of ways the A frame might not line up exactly. Spring shackles need only be slightly off and the movement is magnified by the time you're back at the ball. A few thousandths of an inch inch clearance in the shackles is all it could take to make a difference like that and who worries about a few thou there?
During the heat treatment of springs, it is VERY common for the leaves to "wander" a little. Again, a slight difference would make a 3/4" difference at the ball quite easily.
Just pull the ball into place and do it up. That's what they will have done on the assembly line and they will have had the same things happen during heat treatment etc. Don't overthink this, just do it up and drive. Things will very quickly settle into a "happy" relationship.
