Create Bookmarks in Existing PDF Document using C#

I try to create for existing pdf new bookmarks tree like this

Bookmarks bookmarks = new Bookmarks();
var rootBokmark = CreateBookmark("Root", 1);
var secondBokmark = CreateBookmark("Second", 2);
var child1Bokmark = CreateBookmark("Second", 3);
var child2Bokmark = CreateBookmark("Second", 3);
secondBokmark.ChildItems = bookmarks;

but I have issue when I open in a new object PdfBookmarkEditor.ExtractBookmarks();
I have 4 bookmarks instead of 1. And if I open that file in Chrome and Adobe my bookmarks has different reference to page number.
