With a book from 2 files when creating an epub the master ToC for the epub is OK. There are 3 ToCs - a master one for the book, a ToC for the 1st Chapter, and a ToC for the 2nd chapter. Each chapter has it's own ToC on the first pageo f the chapter that looks ok if it is the first chapter in the book. If you reorder the chapters in the book pane (without making any other changes), the 2nd chapter always includes the first chapter's ToC. If I export the individual chapter files to ePub the ToC is OK. Is there a workaround for this behavior?
Do you "Synchronise the book" after you move the chapter 1 to second chapter location.
