Hi, I need some help,

I'm using the Auto Nav Pro add on and I'm trying to display a breadcrumb trail so when you hover over the menu, it drops. For some reason it's only showing the 'Home' symbol and doesn't branch out. I'm currently having to change 'Subpages to Display' to display all. But it means i have to click on each tab for the dropdown menu to appear.

Can anyone tell me what i'm doing wrong? I've attached 2 photos if this helps. Here's the website header:http://www.turbodynamics.co.uk/test-home/...
