I have an epub document that loads and reads fine in Calibre. I made it from a text document using Open Ofice. But when I use Calibre to convert it to mobi for my kindle the first 11 1/2 chapters disappear as viewed using the Calibre reader.
A TOC appears that matches the entire document, but, of course, with so much missing (or a least invisible) the TOC is useless for those missing chapters.
I'd like to know how to cure this ailment.
