How to stop Pages from making multiple copies of the same document
This is making me crazy. Every time I edit a document, Pages makes a copy instead of just saving what I edited. So I end up having a single document with Copy 2, Copy 3, Copy 4, etc. ad nauseam. These copies are multiplying like the brooms in The Sorcerer's Apprentice! And I can find no way to make it stop -- I need a Master Sorcerer.
I generally leave a document open but minimized in the dock if I edit it frequently (like an agenda), so the dock is now crowded with copies. I'm not using the Cloud at all and I have no docs there.
I saw a question about this answered by Apple Support like 6 years ago, and I couldn't make sense of it. All I want is to shut that process down and have Pages make and save changes without making copies.
