Certain documents "require pages update" when I am fully up to date
Hello... I keep having certain documents on my Mac Air running OS X El Capitan saying that I need to "update pages" in order to view the document. This only happens with some of the documents, but not all. My pages is up to date and so is the computer.
Any suggestions for why this is happening and how I can remedy it would be excellent.
Thank You.
MacBook Air 13", OS X 10.11
