Infinite SEO wrong URL to the XML Sitemap

I have a subsite on my WPMU called lifemasterycoacj.techimpossible.com and I had it previously mapped to peterskaronis.com and since I have removed that mapping and mapped it to lifemasterycoach.co

The URL to the XML Sitemap still says peterskaronis.com/sitemap.xml

How do I fix this and does this cause any sitemap issues?

I still have peterskaronis.com on another subsite peterskaronis.techimpossible.com

Thanks

Peter
