I think the reason for this is, that the game was accidentally created 2 times in the gamedatabase. However because the japanese sales are on one of the games and the NA Sales on the other one, it wouldn't help to delete one of the entries. I think the gamedatabase admins have named them so they know which one has which sales and they will merge them as soon as they can.
Disclaimer: I am not part of the gamedatabase team. (However, I like to help them by adding screenshoots and other stuff.)
