A recent weird bug cropped up on Wikidata where *some* sysops are unable to edit sysop protected pages. Two currently protected pages are; https://www.wikidata.org/wiki/Q5268366 and https://www.wikidata.org/wiki/Q16503.
After speaking with Addshore, it turns out we both have this weird issue. His solution tested out was granting both of us confirmed user flags (log: [1]) which apparently made us able to edit protected items.
This seems like an awfully weird bug which really should be looked into in more depth. Also this is a Wikibase issue as all other non wikibase pages are editable without the confirmed user flag.
