Control Has Duplicate Programs

Came in this morning, fired up the VF1 with no problems. After a little while I noticed that the majority of my programs had duplicates. I noticed this after making major edits to a particular program...started running...remembered another change that needed to be made and hit the rest button. All of the sudden, my program was back to the way it was before I made my changes. Entered into the "select program menu" and noticed there where two programs called O00013. Not only dose the program name match...but the program number inside the program is the same as its duplicate. One with all my edits and one with out. Got to looking, and several of my programs had duplicates. I can switch between them no problem..the control dose not have any alarms...how strange. So I backed up all my programs and wiped the rest of them away. Hoping someone out there can shed some light on this situation. Software bugs? its an 05 VF1 Mocon 17 something.
