Two editions of the same book, No editions of another. > Likes and Comments

I'm seeing two identical editions of my Arkana Mysteries Omnibus 1: Books 1-3, but I'm not seeing the second volume in the series at all on my dashboard, even though it exists on my book list. I'm missing Arkana Mysteries Omnibus 2: Books 4-5. Also, for some reason, my dashboard is displaying an audio edition of Lucifer's Triangle. I didn't think audios were supposed to be included on Goodreads.
