How do I make one wiki the root breadcrumb

I want this to be displayed as my root breadcrumb
http://ecopsi.org/edu/encyclios-paideia/

This is the path of my wiki root http://ecopsi.org/edu/

I tried this because it sounds sort of like my problem but resetting the breadcrumbs in permalinks didn't do anything at all.

Permalinks are now set as following.
Day and name
http://ecopsi.org/2014/09/21/sample-post/

Help please
