Two unlinked editions

[Felikis]

Good evening,

I've been reading the help about "Combine" and "Merge" and I think this action is neither.

RBA is publishing in Italy and Spain "The Sherlock Holmes Collection". Several of the titles are linked in the "More editions" section of the book page, where their counterpart in the other language edition can be seen. But for example, in the case of "La hija del usurero": https://www.goodreads.com/book/show/6... does not have its link to the Italian edition "La famiglia dell'usuraio": https://www.goodreads.com/book/show/6...

Can this be corrected somehow? Can I do it myself or should I ask the superadmin for help?

Thank you very much.
