Help - My EBook is showing under a different author

[Derek]

I see the eBook edition of my book Unicorn Witch is showing under a different Derek White. How can I move it so that it shows on my page?

Thank you in advance.

Currently showing on this Derek White's profile

I've changed it. FYI your name is written with 2 blanks (for disambiguation with others Derek White)

Thank you very much.
