Featured content without content selector

Hi,

I am trying to modify the pages that appear in featured content, but it’s impossible.

I follow the indicated steps in the support page: https://catchthemes.com/theme-instructions/catch-responsive/#enable-featured-content

I go to Appearance> Featured Content Options> Featured Content Settings. I choose the “Homepage/Frontpage” option

Then I go to Appearance> Featured Content Options> Featured Content Type. I choose Featured Content Page.

The configuration options appear on this screen are:
-Headline for Featured Content
-Sub-headline for Featured Content
-No of Featured Content
but no option to choose the pages to display.

Right now it’s configured as “Demo Featured Content” and 3 pages appear in Homepage. I don’t know why they and not others. In any case, I want modify them for others, but it’s impossible.

I have pages with Featured image included.

The page I need help with: [log in to see the link]
