Separate Authors with same pseudonym

[Arisa]

This book, Soul-Burn (http://www.goodreads.com/book/show/13...), is written by "EniGma" ,a Thai Writer. But when I entered "EniGma" , it shows up another writer named "Enigma" (http://www.goodreads.com/author/show/...). How can I sepate these two? They are different authors ,but similar pseudonym.

Thanks

Single-name authors cannot be separated.
