When working with the files from Creative Worship, when I go to the prepare bulletin screen, I have our Stylesheets set to a 'custom' that works best with our printers and ease-of-reading.
If I ever go back to editing the outline and then back to 'prepare bulletin', while the Stylesheet selected may still be 'custom' - the formatting is actually something else. I *think* it is 'UIDefault'.
The work-around so far has been to select any other style, then go back to 'custom'.
