You could try highliting that part of the text in your saved listings and change to a gray background color that matches your template. Then save it, then copy the HTML. You'd then have to go into Ebay to revise, delete all the HTML already there and insert the new.
To tell the truth, I didn't think it detracted from your listing at all, and if you're like me and don't use HTML very often, you might be better off leaving it alone.
