I think my current and hopefully remaining problem is caused by a bug in how the kindle displays an azw3. The epub has blank lines between lines of text in a paragraph, i.e., two line feeds/newlines between lines between the opening and closing p tags. When I look at the azw3 on the kindle that calibre produced it starts a new line where the blank lines are (and doesn't display a blank line). Calibre left the blank lines when it converted to azw3.

If I change calibre's conversion settings to use justify instead of left align then the kindle displays it properly. But I'm fussy and can't abide justified text.

I can fix the epub with sigil's mend and prettify, so I have a solution to the problem.

Is this a bug in the kindle? Seems like it is to me but I'm no expert on this stuff.
