How do I change the editions?

[Hemdiva]

Chinky Pinky Illustrated Children's Book and
Chinky Pinky : A Birdy Adventure are two different books written by me. But they are shown as same books, just different editions. Resulting in the reviews & ratings for the earlier book, showing also on the latest one. This is not right. How do I change it? I mean, list the book as different book, not different edition? Thank you.

Separated the illustrated one.

Other than including illustrations, how do they differ?
