The table of contents of my manuscript became a Preface when I imported it. How do I stop that?

From version 1.9.24, Word's own table of contents, and a contents list you typed by hand under "Table of Contents" or "Contents" before the first chapter, are left out when you import a manuscript, instead of becoming a Preface. BookyAI makes a new contents page when you export. In an older version, on the import screen set that section to "Don't import" in the list on its right, or, if the book is already imported, delete the text of the Preface on the book's page.
