niksng on "[Plugin: WordPress SEO by Yoast] Draft posts in Xml sitemap crated by Seo Yoast Plugin"

Hi, I have some posts that were published but after I have drafted them they still show in xml sitemap and google show them as broken links now. What can I do about it. How can I stop them appearing in xml sitemap.
