Well one of the problems is your redirects which makes it hard to tell where you want the tabs to go.

The main problem is that you can't have tab links go to non-subpages, the template doesn't work with that. If you redirect a subpage to a non-subpage the template still wants to look for a subpage with the tab name on the non-subpage which doesn't exist, hence the red links.

You either have to do it the way the template wants or use a different tab system.
