With a ToC of 53 entries and 5 pages, it is still fairly short. I have a book somewhere that has about 30 pages.

It works perfectly.

I can think of two reasons for this behaviour.

It is possible there are errors in the TOC. Opening a book in the calibre viewer (I think that's what you are using on the computer) is not a good test for errors in the book.It is actually doing a conversion to a common format and fixes some things while doing this. This common format is almost the epubs standard, and it means that even for epubs it will fix some things. Opening the epub in ADE is likely to show any errors. Running epubcheck or opening in Sigil and using its check should show if there are TOC errors. If this is the case, you can fix it with a conversion in calibre, using the TOC tool or in Sigil.

The other possibility is if you sent the book to the ereader, let the ereader processed it and then changed and resent. When the Kobo ereaders first see a book, they process them and put details in the internal database. This includes the TOC which is then used for navigation. You can replace the book successfully, but the book is not reprocessed. If the structure of the book, or the TOC changes, this is not picked up and they will be out of sync. The only thing you can do is delete the book and send it again.

If you would like, I can take a look at the book. If it is available somewhere for free download, post the link. Otherwise, send me a PM with a link I can get it from or to get an email address you can send it to.
