A issue arrises whenever a user is in a product category and starts using the filters and after that wants to clear all of the filters. The user clicks on “Clear filters” he is always being redirected to /shop/. Normally the user should stay on to the product category page he was on when he started filtering just without any filters selected.
A live example can be seen on: https://verlichtingkopen.com/ /binnenverlichting/hanglampen/. After selecting some filters and clicking “Clear filters” afterwards it will take you to https://verlichtingkopen.com/shop/ instead of the original category page https://verlichtingkopen.com/ /binnenverlichting/hanglampen/
