Filters doesn’t apply on attributes

I noticed that filters doesn’t apply on attributes. Filters apply when I select a brand logo perfectly. I followed these steps to fix this problem but it didn’t work out. https://support.yithemes.com/hc/en-us/articles/4910132227217-Filters-not-applying

Here’s the link to the website where you can see that selecting brand logo works just fine, but selecting an attribute doesn’t apply a filter. https://devinera.com/grindinio-sildymo-kilimeliai/
