Thread: Breadcrumbs say Home » Listings » Listings » Category?

Breadcrumbs say Home » Listings » Listings » Category?

Is there a reason why the breadcrumbs say "Listings" twice? Especially when they both have the same link?

Vantage Permalinks I Have:

Listing Base URL - listings
Listing Category Base URL - category
Listing Tag Base URL - tag

If I change the listing base url to listing I get - Home » Listings » Category... So why do I get double if I add an "s" ?
