I currently have 8-10 different *.ofocus files listed in my OF dock icons context menu. I have, however, been looking at some old archived documents I exported and I have some which I use to perform R&D testing without compromising my main OF document.

Have you performed an export or copied your OF document? From my experience this signifies that your system has two different OF documents saved somewhere. Try doing a spotlight search for them. You can open both at the same time if you need to compare them.
