I had 473 pets, then I captured three of the new ones and I went here to update my list, but after the reimport is now said I had 472 pets and two duplicates. After some investigation I found:
1) The pet that warcraftpets thinks I have lost if the 'Darkmoon Balloon'.
2) The duplicates are correct. The game seem to have given me two more Mr.Bigglesworth.
3) None of the new pets are imported. I have now captured all four new pets on the island and none shows up here.
The cause of #3 seems to the armory that's slow because it doesn't list my new pets either. However, it does list the Darkmoon Balloon in my collection yet here ít seems I have 'lost' it
