Breadcrumbs go only Home > Final Destination (no intermediate steps)

Hi everyone,

Breadcrumbs are appearing at top of pages, but they go directly from "Home" > [final destination topic]. 

In other words, they are no longer breadcrumbs, per se, since they show only "Home" and then the final destination -- with none of the steps (i.e. books) in between. They are not listing the books -- just "Home" and then the topic in question, and leaving out which book the topic is in, or any other steps in between.

I think I screwed something up while messing around with master pages.

Any help is greatly appreciated.

Thank you!
