Hi,
I checked your issue, and it seems that the number of copies (and probably also other settings) is a book property.
When I have a new book, the default number of copies is always 1.
When I set this to 2 and print the book, close it and open this book again, the number of copies is 1 again.
When I set this to 2 and print the book, make a change in the book, save it and close it and open this book again, the number of copies is still 2!
Therefore, change the number of copies in your book to 1, make a change in the book (e.g. update), then save. Now the number of copies should be 1 again.
Best regards, Winfried
