Not sure what do to about it or even if there's any point in doing anything.
That is exactly the answer I got at some repair seminar back in the 80s at one of the bike shows. A slight misalignment due to manufacturing inconsistencies is the exact wording I think. This pops up all the time. High end, low end, doesn't seem to matter. Bottom line is as long as the function is not affected, live with it.
