Forum:ME1 End Save Issue

Back on November 17th 2009, I finished a playthrough of ME1. Earlier today I finished a second playthrough with that same character after importing him using new game plus. When I go to the importer in ME2, it says that the last played date for this character, the one I finished today, was November 17th 2009, the same date I finished his first playthrough. I tried reloading some saves from just before the last fight with Saren and finishing the game again, but those endgame saves also say they were completed in 2009. It's really weird. Even though the problem is actually pretty minor, and the file can be read and imported into ME2, it's got me concerned that there may be other things wrong with the save, that maybe some of my choices aren't saved correctly or something. Has anyone else had this happen to them? Should I be worried? I really don't want to start an ME2 (let alone ME3) run with this save if something's wrong. Thanks for any help you can give.
