Please note that a sitemap is only one of many ways Google discovers the URLs of your site. If Google discovers the URL through other means, it may not cross-reference your sitemap to check if the URL is there. Hence the “No referring sitemaps” message.

Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
