how to delete second descriptors of my book on Goodreads

[Graham]

Hi, 2 descriptors (metadata) of my book Call Game (authors Graham Elder & Laura Cody), currently exist on Goodreads. I would like to keep the version with the appropriate description and reviews and delete the other. How do I do that? It's the same edition of the book due for release on 23rd October.

Thank you

Graham Elder.
