First chapter converted in a image and rest of it disapears

Hi,

im creating eBooks of mi notes to study with mi Kindle, so I make the notes in Writer and convert them with the Writer2ePub plugin.

When I try to convert with Calibre form ePub to mobi (old, or both format) or to azw3, it creates a pic of the first chapter and the rest of it disapears and jumps from the pic to the second chapter.

If I convert the ePub with Kindlegen (2.7) and then with Calibre to azw3, then it don't happens.

Here a sample file: http://ge.tt/8ZDx1eT/v/0?c

Any solution?

Thanks for all :)
