Sitemap indexing supercache

My sitemap and now google webmaster tools, is showing results for supercache.

A sample url: http://www.mysite.com/wp-content/cache/supercache/mysite.com/sample-page

I use the All in One SEP sitemap.

Has anyone else had this experience, or have any insight to the problem, and recommendations what do?

Thanks.
