Breadcrumbs problem

It appears that topics have memory, are stubborn, and don't want to change.

I create a new book in a project's TOC and linked the book to a topic so that clicking the book displayed the linked page as well as expanding to show the topics in the book. 

Then I decided to move some topics not originally included in the book into the book by clicking the right arrow on the TOC to have those topics become part of the book. 

The PROBLEM:  The topics that were originally in the book show the correct breadcrumbs. Those that were not, show breadcrumbs but skip the book name in their breadcrumbs, meaning they show the breadcrumbs as they originally were when not moved into the book. WHY, WHY, WHY????

I believe this project that I inherited has had several tech writers working in it since it was first created. It also is the merged product of 2 previously independent projects, I'm told. I think these two projecters were simply compbined vs. merged. But the who thing is driving me nuts.  Please help.

The breadcrumbs should be Technical - Report Writers Skills > A-Z Skills > [topic name]. Some topics persist to show Technical - Report Writers Skills > [topic name].
