Why are categories duplicated in breadcrumb breadcrumbs?

Question

opencart

Duplicate categories in breadcrumbs, although the breadcrumb path becomes correct when moving to a product.

The link to the category (nc) is also formed correctly without duplicates.

This is how breadcrumbs look when you switch to a category from a catalog or from a product:

Product catalog> Connectors and accessories> Network connectors> Product catalog >Connectors and accessories>Network connectors> Network connectors Kimber Kable

or like this:

Product catalog> Product catalog> Connectors and accessories
