Woocommerce product categorie not linking

Hello,

My woocommerce product categories do not link correctly!
when you go to a category the 404 page shows up.
I linked the url https://www.golden-eight.com/product-category/earring as menu.

We also have the site running in german where the categories work well!
I linked the url https://www.golden-eight.com/de/produkt-kategorie/vergoldet/ as menu and it works like it should.

Does anyone know what the problem for that is?
