Just saw this old one start up again as well. Rules set up for just 8 categories were showing up on all posts, all pages, even on Media Library items.
Had a separate set of group rules for the taxonomy of category (added fields to category pages beyond description and name ) and those were not impacted.
So in case it helps troubleshoot (long shot) maybe there is a prioritization? or more likely it just doesn’t impact taxonomy edit pages.
