Infinite SEO xml has 1000's of incorrect URLs

Hi,

I am checking my site map links and have found approx 15 links that are good. They are the main site's blog posts and some pages.

After that there are 1000's of incorrect links to what appears to be buddy press groups and sub tabs.

domain.com / item / [buddypress page]

See for yourself: http://tradr.com/sitemap.xml

Does anyone know why this is happening?

Cheers,

Johnny
