Listing Category widget unexpected behavior

Hello!

I’m experimenting with Classified Listings with Elementor for a project.

All is OK but I’m having an issue on the home-page. There I placed the Listing Category widget, looked into each setting and expected to see the listing I had published. That works.

When I go to the page and click on a category link, it takes me to the Category page, but I get the following:

The page can’t be found.
It looks like nothing was found at this location.

What am I missing?

I’d like to see the listings of the category on the page, like this: https://ipanema-rio.com.br/ipa02/saude/

Thank you!
