I think I've figured out the problem. As I have no cards from Shadows over Innistrad, I've outconfigured the Innistrad block completely. It seems like the legality settings take those configurations into account and because my copy is from AD&D Commander, it is regarded only as Commander legal. In my opinion the legality should be unaffected by block configurations and stay constant.
