Formatting not "sticking" in the (new) cover wizard
I am having a strange problem with the cover wizard. There are bits of text (in the editable boxes) that are not following the formatting styles (font size/ italics) that I am trying to apply. The formatting is changing as it should, but when I click out of the box and request a preview/ print ready doc, the new formatting style isn't getting applied. Any ideas?
