I have configured a Top Link bar on my SharePoint 2010 site. It looks fine for my pages. But as I navigate to application pages the navigation levels split up e.g MainHeading/Heading1/Leaf Nodes. This is my menu structure and when I open any application page it splits up in two Main heading and other is Heading1/Leaf Nodes.
I am not able to find out whats the reason behind this. As it looks fine on custom pages.
This is how the menu looks on custom page
This is how top link bar looks on application pages.
