Breadcrumbs showing "Product Category" as text
Since today I currently have the problem that the Breadcrumbs on my product pages show the text "Product Category" instead of the actual category. Before today, it worked as it should. Please see the attached screenshot or the link to a product page: https://www.leukebordspellen.nl/product/keer-op-keer-2-spel/
How do I solve this?
