Sitemap help

I deleted my sitemaps. My new sitemap is listed as
https://www.lasvegasworldnews.com/sitemap.xml

and I thought it was fine and submitted to Bing.

and then under it I get this
https://www.lasvegasworldnews.com/sitemap-posttype-post.2014.xml 0 Unknown 3/24/2014 404 (Not Found)
https://www.lasvegasworldnews.com/sitemap-posttype-post.2012.xml 0 Unknown 3/24/2014 404 (Not Found)
https://www.lasvegasworldnews.com/sitemap-posttype-post.2013.xml 0 Unknown 3/24/2014 404 (Not Found)
https://www.lasvegasworldnews.com/sitemap-home.xml 0 Unknown 3/24/2014 404 (Not Found)
https://www.lasvegasworldnews.com/sitemap-posttype-page.xml 0 Unknown 3/24/2014 404 (Not Found)

But if I type in the URL’s myself, there is information there.

Can someone help me please? Why are the sitemaps not showing up.

I am using XML Sitemap & Google News feeds. Was using wordpress seo sitemaps but has big problems.

If I submitted the sitemap for the index and it was OK why are all the other files not OK but yet I can see them?
