Breadcrumbs problem

Hey, I’ve got a question concerning the breadcrumbs feature.

I’m only using main categories, no sub categories.

Let’s say there’s a product called “Test” in the “Cupboards” category. The Breadcrumbs should normally say

start > catalog > cupboards > test (product name)

Instead, it says

start > catalog > test(product name)

I’m aware there’s another thread with a similar problem (in that case, it seemed to be due to subcategories though) -> https://wordpress.org/support/topic/breadcrumbs-question-2?replies=4

Thanks you in advance!
