The  categories in Category:Authority_control_maintenance are used to help with transition of Template:Authority_control identifiers from Commons to Wikidata, so that Authority control template does not have to keep and maintain all the identifiers but only a link to Wikidata where they are held and shared among all the projects.  The categories there depend on comparison of Commons identifiers with wikidata ones. However I run into a curious problem where some pages are in some category, but that categore does not list them. For example Creator:Titus_Livius lists that it belong to Category:Pages_using_authority_control_with_all_identifiers_matching_Wikidata but that category does not lists it as one of the pages that is part of it. Other pages like that are: Creator:Alonzo_Rodriguez or Creator:Perrin_Remiet .

The only solution to the problem I found is to do an edit to the creator page, or run Pywikibot/touch.py if I had a list of files that need it. I guess some kind of event is needed to trigger page refresh and with activation of wikidata arbitrary access, we run into a problem that the event is happening on Wikidata and does not trigger the refresh on Commons. Page Purge does not seem to help. In the meantime I think I have about 100 pages in such a limbo state, but I have no way of finding them, other than running “touch” on large number of pages.

Any ideas what to do? Is that a bug that should be reported, or new norm. Does Wikipedia and other projects that used wikidata for a while run into it?
