Infinite SEO with Domain mapping

I am testing Infinite SEO in combination of domain mapping on a test site.

We have a test site called http://krauseonline-com.mystudioengine.com. We have mapped http://krauseonline.com to this site. When I access http://krauseonline.com/sitemap.xml I can see in the xml that instead of using my mapped domain name it provides the true site name of http://krauseonline-com.mystudioengine.com. How do I get the sitemap to use the mapped domain name?
