Have you tried separating your breadcrumbs into separate navigation menu's and separate navigation widgets into their own layers?
ie.
Layer name: Not Blogs
Match: not url(~/blog1*) and not url(~/blog2*) and not url(~/blog3*)
Widgets to include: Breadcrumbs for pages
Layer name: Not Blog1
Match: url(~/blog1*)
Widgets to include: Breadcrumbs for Blog1
Layer name: Not Blog
Match: url(~/blog2*)
Widgets to include: Breadcrumbs for Blog2
Layer name: Not Blog3
Match: url(~/blog3*)
Widgets to include: Breadcrumbs for Blog3
