Disappearing filters

Hi,

I’m using your filter and I’m having some troubles.
Namely, when I setup the first filter, after loading, all of the filters disappear. There is no change if I use drop-down or list style.
I’ve tried looking the answers that your customers have been asking but I can’t seem to find a solution.
As far as I see, I have only one widget sidebar store page that is present at all times.

Here is my store: https://sigedon.com/shop/
(You can login with username: guest password: 00guest00

I’m using Motors theme, found here: https://themeforest.net/item/motor-vehicles-parts-equipments-accessories-wordpress-woocommerce-theme/16829946

Thank you very much for your help,
Kind regards,
Marko
