Goodreads Choice Awards Book Club discussion

I have accidently put bookshelves in my list that I have no interest to add books to. These were due to challenges that no longer exist. Does anyone know how to delete these bookshelves? Thanks for the help!!

Just go to My Books -> then at the top left, click edit -> then find the shelf you want to delete and click on the X next to the name of the shelf.
