Mam problem z zagnieżdżonym łączem bezpośrednim. Mam taką strukturę adresów URL:

Catalog -> Category -> Product

Moje adresy URL to:

• www.domain.com/catalogs (dla katalogu archiwalnego)
• www.domain.com/catalogs/%catalog% (dla pojedynczej strony katalogu z listą kategorii)
• www.domain.com/catalogs/%catalog%/%category% (dla pojedynczej strony kategorii z listą produktów)
• www.domain.com/catalogs/%catalog%/%category%/%product% (dla strony pojedynczego produktu)

W WP Backoffice i Frontoffice wszystkie adresy URL są poprawne, jedyny problem, jaki mam, to odwiedzanie strony produktu, na przykład:

www.domain.com/catalogs/catalog-001/category-001/product-001

Tam otrzymuję błąd 404. Mój kod jest następujący:
