Here's the conversion log going from mobi to epub. Again, I just get two pages for a final result, the front cover and a blank page (just like the mobi.)
For some reason, I am having trouble converting the original file from azw to epub. I can do azw to mobi, then mobi to epub.
I fear my calibre knowledge is lacking here.
Spoiler:
Convert book 1 of 1 (The Holy Bible, English Standard Version)
