Filters are not updating as expected

Hello! We have the pro version installed on this site: https://thedna.org/gtld-resource-directory/

It works really nicely when the first category is selected from the dropdown, however, if you wish to navigate to another category, the content isn’t updating.

If you click from “All Services” to “Advisory & Strategy” and then back to “All Services” – you’ll see the results do not adjust. Also if you watch the URL, it doesn’t change.

Would appreciate a fix on this.

Thanks so much.
