There is another book, which is a duplicate of the 7th volume in the series put to the "Deleted" status assigned with another ISBN10 related to the whole series: 5770753366.
The correct 7th volume is “Public” and assigned with its proper ISBN 10: 5770761628.
The problem is that the "Deleted" duplicate was assigned with the ISBN13 9785770734799, which is being generated on the basis of the proper ISBN10 5770734795 for the first volume instead of the ISBN13 9785770753363 which would be generated on the basis of ISBN13 5770753366 assigned to it.
This situation makes it impossible to add the proper ISBN10 5770734795 to the first volume. I couldn't find the answer where I should address the issue and I can't resolve it myself.
It has to be assigned with the ISBN10: 5770734795.
