'Untitled Chapter' bug for all chapters after kepub conversion

[mwessman]

Hello,

I have a regular EPUB book that works pretty well in EPUB format on my Kobo Libra, but I decided to convert it to KEPUB to make it work a lot smoother. The only issue I have is the chapters seem to not work anymore. In the EPUB format I could still see the name of the chapter I'm on at the bottom of the screen, but after converting it to KEPUB, it just says 'Untitled chapter'.

Oddly enough, the ToC works fine and lets me jump to the correct chapters with the names included without any problems, but when I'm actually on the chapter my Kobo device gets confused and just says 'Untitled chapter'.

This is not a critical bug and doesn't necessarily affect my reading of a book, but jumping between chapters and wanting to know what chapter you're on gets quite annoying, especially with long books with lots of chapters.

The only thing I used was the KoboTouchExtended plugin on Calibre and clicked the 'Send to device' button. Nothing else.
