   | Possibly, the program did an auto-save (which it does after a few minutes).  So if you open a previous project and work on it, after a few minutes the program will auto-save a copy - it doesn't overwrite the original - but later when you save with a new name, you'll find you have this extra project file which looks like your newest file, but has a name similar to your original file. 
 Try doing a save as immediately after opening an old file, so the old file name won't get "re-used".
