I have a page which has had 2 versions; the original version is causing some issues with a macro, so I wanted to just delete it. When I go to the page history, I can see a Delete button next to version 1, but when I click it, the old version doesn't get deleted - the page refreshes, but both versions are still there. No error messages on the screen, and nothing in the console.
Is there some extra permission I need? Or could something be blocking it from deleting?
