Goodreads Librarians Group discussion

Hi folks. Hoping for some guidance here . I have a published paperback and kindle edition of the same book on Goodreads. The kindle edition has an error in the subtitle …it’s missing the first three words. Because of this Goodreads thinks it’s a separate book or separate account and it’s causing issues with trying to do a promotion Can any of you tell me how to edit the subtitle on the kindle page?
Thank you,,,,,
Downstairs at the White House: The Story of a Teenager, an Oval Office, and a Ringside Seat to Watergate

The book was combined with the other editions, so no, GR didn't think it was separate. However, I added "The Story of" to the subtitle.

Wow, Thank You so much!! You have made my day. Don.
