Separating editions

[Esha]

I have recently had this book picked up with a new publisher; the new version is extremely different from the old self-published editions plot and writing wise. However, it seems the version labeled "Avon" (the new publisher), show up as editions without covers under this book. Is there a way I can have the two "Avon" versions separated from this book so that they are their own "Offtrack"? I tried using the separate feature under combine editions and it would not allow me to. Thank you!
