I found out when I select Tabular View, page 8 comes up in the breadcrumb REPORTS, but when in Hierarchial View, it does not show. I will delete it in the Tabular view and then create the breadcrumb region in page 8.
Possibly. I think it would depend on how you delete breadcrumbs - I delete the regions on the pages and then the breadcrumb definition. It would help, as you say, if there were a means of checking for orphaned items. Application Reports, Page Components, Regions by Type, "Display Type, and Template" will tell you if there are any breadcrumb regions in your app - these are shown as Region Type "Menu" - but it doesn't show if these regions are actually linked to valid breadcrumb entries
