Well, that's just how the template worked, and it gives it a bit more uniformity. You could always just download both versions, and "copy-pasta" the back of the Black Label version onto the Greatest Hits cover. I've done it a few times myself for Dreamcast and Saturn games.
By the way, Shenske, is there any chance that you might make a vertical version of the Final Fantasy Tactics cover? Of course, do it whenever ya wanna if ya wanna, it isn't necessary. It just something I think I'll be going for.
