Archives page showing extra (empty) blog entry box

I'm setting up a site using a theme I purchased on ThemeForest. An issue has come up and the theme author is not responding.

The issue is that on the news page (blog archives) an extra box is showing up as if there's a persistent empty blog entry, only there isn't.

Can you suggest a fix?

Thanks,
