Remove "authors"?

[Elizabeth]

Hi,
I was just wondering if it was possible to remove "authors" from a book listing?
The kindle edition of the following book has Kim Richards and Amanda Kelsey listed as contributors, when it seems unconventional to do so for this sort of book (YA Fiction).

I have tried to remove them but it came up with an error.
Thanks.

confirmed they were the cover artist and editor on amazon. you are right, goodreads does not grant cover artists or editors for single-author works 'author' status. removed.
