Help! Adding a book to a series

[Hanna]

I'm trying to add Utterly Irreversibly to A Good Wife series but it won't let me :(
I'm going into Girl Wife Prisoner and clicking the series title (A Good Wife) and hitting 'edit' but it won't let me add anything. I'm not sure I have access to this.
Can someone help, please?
Thank you! :)

Added the novella to the series. Novella's are not showing in the series on your author page; they show on the book page and on the series page: https://www.goodreads.com/series/1602...
Authors can't add books to series.
