Yup, I already checked all that. I'm really particular whenever I'm adding new books to my NC and making sure that the metadata is correct. On the nook, it has always sorted by LN, FN but is presented by FN, LN. I didn't have a problem with these books until I did the plugboard, which makes me think there is just some sort of glitch. Unless I'm doing something wrong, which I don't think I am, but if I am then it's not an obvious one to me (I'm definitely not any kind of pro at Calibre).
