AS was posted above, the OCLC record was started from the original title of the book. Ann changed the name (or her editor did) after the cataloging had been sent out for use.
Yeah, that all does make sense. The worst we’re looking at here is that the person tasked with updating to the new title decided not to, figuring it could be explained away as an “oversight.”
But nothing for us to get our noses bent out of shape over.
