accidentally combined my books

[K.V.]

I originally published this book with the same title (pink cover) in August but today I released a revised edition with different content and a new cover (blue)
I accidentally merged my editions and now this new cover has all my old reviews from my previous book. How do I unmerge them so this edition just published has zero ratings and reviews?

Different editions should be combined, it is correct as it is.
