Extra Space after label

Why is the system creating an extra <p> tag after the label, like this:

<div>
<label for="Site_features">What does the site include?</label>
<p></p>

It throws off the layout and makes it hard for the use to figure out that the labels goes with the list below it.

ANy fix for this?
