How do I clear this up (two authors with similar names)?

I'm having trouble with these two authors. When I found this page ( https://www.librarything.com/author/whiteheadneill ) all of the works were attributed to a Neil L. Whitehead. I figured out that one work, My Genes Made Me Do It, was authored by a Neil E. Whitehead (with Briar Whitehead), but I can't figure out how to get rid of its association with the name "Neil L. Whitehead."

"Neil L. Whitehead" and "Neil Whitehead" were combined together. I've separated them, so now you can find "Neil E. Whitehead", who writes as just "Neil Whitehead", here: https://www.librarything.com/author/whiteheadneil
