Hello–I, too, am getting extra paragraph breaks in the [description]. I have it set to “No line breaks, no auto paragraphs,” and have manually added line breaks in text edit window.
Still, the description gets its own paragraph breaks, and weirdly if I add a text descriptor, like I have for the other short codes, I get yet another line break. I see the p when I use Firebug, but I can’t seem to get rid of it by changing the CSS margin. Can you please advise?
