Book wrongly merged > Likes and Comments

I've added the play script of "The Girl On The Train" (ISBN 9780573132131) to my books and noticed that nearly all the reviews refer to the novel, not the play.
These are distinct works. Have they been merged?

Yes, it was combined. Merge means to delete here on GR, just so you know.

I've removed one other play, but your one is being stubborn and isn't separating.

I've added the correct authors - the adapters, and I'll keep on trying to separate it.

Still not separating.

If I can't get it to separate in the morning (2am here) I'll forward it to support.

And its done, but there is obviously, to me, another edition that shouldn't be there, as well.

Found another three editions that didn't belong. 2 plays & a Penguin Reader.

Separated from the main book.
