It happens occasionally when studios reuse a UPC number. Unfortunately, Profiler doesn't handle these very well. What you can do, is enter it via the disc ID and submit it that way. (just place the disc in your drive and Profiler should ask you if you want to add it. Otherwise, you can go to add like you would via UPC and chose "by inserted disc."

There is a chance that that disc id has already been entered, so you'd have to keep any differences local.
