There are instances where a fn tag will have more than 1 p tag, but if it does, that typically means this groom won't apply to it. Usually if there's more than one <p> then it normally doesn't have a <label> tag. Otherwise, there was a slight merops formatting boo-boo, and some manual work would need to be done to fix it regardless. But I can tweak the groom to be safe, if you think it's appropriate.
