Uncombine author?

I am sure that H Raven Rose and Raven Rose are 2 different authors. I also find that there is a Raven Rose who is a narrator. I do not know how to "uncmbine" an author. I'm sure I'm just missing the obvious. Thanks for the help.

I’ve separated them.

If the narrator is not the author, we will need to split the newly created author.

PS: for future references, you want the Helper Hub on the author page. :)

The newly created record is here: https://www.librarything.com/author/roseraven
