Help with google webmaster sitemaps

Hello, can anyone help with this little question,

I uploaded 2 sitemaps to google webmaster, one of them is showing items as web, images and mobile, and the other only shows web.

I used the same software to create the sitemaps, and the sites are very similar, i can't see any difference in the sitemaps, so why the difference? thanks

Panther28,

You may have either specified a namespace or WMT did for you when you submitted your sitemap. Or, there may have been file extensions (for images, mobile and video) included in one sitemap and not the other.

Perhaps you can find an answer here,
