Hello Razy,
Divi created a new element just for the plugin, I tried using that but it didn’t work, I also tried with the widget bar, like the plugin showed in the “Edit Filter” section, and it didn’t work either.
But I noticed that filters worked when using the widget bar element (Divi) and a shop element (Divi) in all other pages different from the main shop page. I was testing the filters in the main shop page. They didn’t work only in that page.
As long as I use other pages different from the main Shop page, it works perfectly.
