Game Collection List Anomalies

Hi, I am new to the site but really enjoy it so far and hope to be a contributing member. I am a PS2 collector and intend to use listal to track my games. So as I search for the games I own I notice that the numbers are off. By my current calculations I should have 614 games but the link on the left hand side is labeled "Own (611)"... OK, it's possible I missed a couple. But when I click on the link it shows "609 Items listed"!?!?! Whatever, I log out for the night and when I log back on the next day and they both say "610"! Great it sorted itself out, so I begin to add tags to the games and I come across what I believe to be one of the problematic games. "American Chopper". When I click on the title it brings me to a "Could not find product ID" page. I then assume my next logical step would be to add the game again so it would have a product ID. I surf to "Amazon.ca" (not sure if the .ca part has anything to do with it) and find this ASIN: B0002B90SU. It gives me message about it being added to the collection but the link still brings me to the "Could not find product ID" page and furthermore the numbers are messed up again!

Any information on how to deal with this would be great because not being able to tag/rate even a small percentage of games kinda renders all the tagging useless IMO.

I've removed a bugged entry from your lists it should now show to correct number. Let me know if you find any other problems.
