single product filter doesn’t work

Hi there,

I have bought the filter plugin but when I want to select a category it doesn’t filter the products from the category.

It also shows to erase all filters and only one is selected. What am I doing wrong?

Also, a single product has vanished now when I click on an individual product… please see this whole filtering thing here: https://wearitdesign.hr/proizvodi/

I also want to remove these filter labels: https://prnt.sc/kdH2JfhYNcC2 How to do it?
