There is a problem where the breadcrumbs link to non-pages.

https://www.hansonrivet.com/tools-machines/tubular-rivet-tools-machines/pneumatic-rivet-squeezers/

Breadcrumbs:
Tools & Machines >> Tubular Rivet Tools & Machines >> Pneumatic Rivet Squeezers >>

There are no "Tools & Machines" or "Tubular Rivet Tools & Machines" pages, so these should not be links.
