Featured Listings in Slider doesn't work

When I create a custom shortcode slider show and pick my featured listings, All of the listings render in the front end and not just the featured.

Even in the preview in the admin it shows a listings which wasn’t chosen as featured.

Shortcodes in general are a mess.

Tried to do a custom listing and add some filters to show by custom attributes but the filters don’t work there either and show all the listings
