Sitemap seems to pick up just the main site

Site: negotiari.com

Sitemap: http://negotiari.com/home/wp-content/sitemap.php

When I look in Google, I only see 14 pages. This covers the main site, but not all of the subdomains. While Google is finding all of my tags and pages, I would have expected Sitemap to show everything. The http://negotiari.com/home/sitemap.xml file appears to be blank as well.

Is this normal behavior or do I need to modify something?

Thank you
