post-sitemap.xml includes two homepage URLs

Hi!

I have problem, i think.

For some reason, my sitemap includes two home page urls. Could this confuse google?
Please see: http://rnbxclusive.biz/post-sitemap1.xml

Tried to delete the plugin, but reinstalling brought up all the old settings…

Could someone help me with this matter?

thank you
