What have I missed and need to learn?
What you may have missed is that calibre remembers conversions settings per book. If you go to preferences - common options and change the settings these settings will be used for all future new conversions. Redoing old conversions may use old saved settings. When redoing an old conversion either drill down into the conversion and make the changes or click the "Restore defaults" button at the bottom of the conversion page, see attached.
