I thought the OP was saying that he tried to add a book to the first profile but the ISBN was in use on the second profile. That would presumably be an attempt to add an already existing edition or a need for an alternate cover edition.
When I looked at the two author profiles, it seemed much more likely that the OP wanted to create the only book that was on the first profile, for the second, which contains several works. So I just changed the author name to match, and magic happened.
In that case I can just edit the author name for you....done. Let me know if I misunderstood though :)
