Author Dashboard Missing One Book > Likes and Comments

Why is this book missing from my Author Dashboard? I would like to have it added please. I tried adding it but it said the isbn belonged to Wendy Kendall so I couldn't add it, but I am Wendy Kendall the author and I was trying to add it to my Wendy Kendall Author Dashboard. Thank you for any help!

Please don't make multiple threads about the same issue.
