Combine editions and remove one erroneus edition

[Ricardo]

Please, add the Catalan edition
https://www.goodreads.com/book/show/3...

to the main book with all the editions
https://www.goodreads.com/book/show/6...

And this one should be removed
https://www.goodreads.com/book/show/3...

Thank you very much and sorry for the inconveniences.
I tried to combine them and failed

Editions combined and blank edition set to be deleted.
There's a small green link for "Add a New Edition" below the description of any book. If you use that, the new edition will be automatically combined with the others.

Thank you very much for the help.

The problem was I saw the green link after having created the book edition. When I tried to add it, I created the blank edition unintentionally. I did not want to try again to avoid mess even more what I have done.

Thanks again.
