Newly manually added book links to wrong book & series

I'm having trouble with this book: http://www.librarything.com/work/12431941/book/198324580

Added it manually yesterday, because I couldn't find it through search. Used the ISBN13 9789402314601, but then it turned out that it got linked to Deon Meyer's 7 Days.
But De stad van de tsaar van Martina Sahler is a completely different book. Can't get the Meyer link or the Griessel-series out and the St. Petersburg (#1) series in. Not even by manually adding it again, not using the ISBN 13, but the 10: 347135154X. I did not want to leave the ISBN empty, for the book has one. This link goes to the page/shop (with all the details) that I purchased it from: https://www.bol.com/nl/p/de-stad-van-de-tsaar/9200000124028346/?bltgh=nH8GAbZeKy... where you can see the ISBN as well.

I have no clue whatsoever why the Sahler book is connecting to a Meyer book. Can someone please help me?

That seems to have been a faulty combination issue. I have removed as many of "Stad van de Tsaar" from "7 days" as I could find. (Unfortunately, same ISBNs sometimes get used on very different books. It's icky).

ETA: Because your link includes both the work number and the book number, the mix up will still be shown from there. Your book should now be at : https://www.librarything.com/work/20573843

Closing.

Tried the link and the right book with the right original data is now showing.

Sorry to be this late in my reply. My week has been very hectic.
