Hello,
that widget is only a simple WooCommerce category link menu and not a filter widget: It does show all products of the clicked category and not a filter for only the listed (and e.g. pre-filtered) products on the current page.
A better example would be this brand filter link:
https://woodmart.xtemos.com/shop/?filter_brand=eva-solo&demo=
As a logical consequence, it would be very useful to have a possibility to filter them by category – in this example it would be: Accessoires / Clocks / Furniture / Toys.
Especially with more than only this few demo products, a category filter would add a much better user experience.
