Data from the item for the artist and Boston are included in the file
pages. So changes to those pages can have an influence on the file
page and are therefore shown to you. (The granularity of the change
tracking is not good enough to tell those cases apart from the ones
where it isn't useful meaningfully.) We need to improve this but I
don't have the plan yet for how to do it properly.
