Merging two books

[Gjalt]

I tried to merge the next two books, but it didn't work:
https://www.goodreads.com/book/show/1...
https://www.goodreads.com/book/show/1...
It's the same book, one with the right isbn10, the other with the right isbn13.
Can someone do this for me?
Then I can complete the data because I bought this book.
Best regards,
Gjalt

Thanks David,
I read several post, but not this one.
I followed the link on that page: "please take a look at this post." and came on the next post:
https://www.goodreads.com/topic/show/...
The last link there in "All the issues raised in this thread still apply." seems to be a bad link, so I couldn't read further.
But as far as I can read English (my third language), I have to post my request to the the staff, because only they can edit this information?

Yes, only staff can edit ISBNs. You will need to contact support.

Thank you for the direct link David.
