Book not linked to right number in series

[Mary]

This book:
https://www.goodreads.com/book/show/3...

has been put with the editions of book 4 in the series. But it is actually book 5. (look at this one which is linked in the right way: https://www.goodreads.com/book/show/3...).
Can somebody fix this?

Thanks in advance.

Separated "Onbetrouwbaar" from "Beautiful Secret", and combined it with "Beautiful".

Also left a librarian note about the series numbering being different for the Dutch edition.
