no breadcrumbs except Home link

I've enabled breadcrumbs, but no matter how deeply into the menus I go, I only see the Home link. I am NOT using primary links for my menus because this is an international site (www.gallaghersequestriancentre.com -- but note that I've turned breadcrumbs off again) with 3 language-specific sets of menus. Could that be the problem?
Thanks!
