Cannot merge editions because author profiles are separate

[Liina]

I want to merge two books as one is a translation of the other but they are attributed to different authors. I tried editing the author but it did not change anything. How can I fix this?
The edition I want to merge to the one noted above is https://www.goodreads.com/book/show/3...

Done.

You needed to add spaces between the authors names.
