Hi bgroup99,

What is happening is that your categories with "child categories" are blank links. Your CSS menu is still functioning with the breadcrumb, but since there is no page to load when you click it, it loads your main_page instead.. probably as default.

The quickest solution that i can think of is to unlink any category that is a bearer of category children, while maintaining the mouseover. That way, you can view those cute son and daughter categories.
