Hello there,

I hope you are doing well today.

There should be an option available for you to select the category of posts used to display the featured images in the slider.

Please go to Appearance > Install plugins and install all the plugins available there for the theme. Also go to Dashboard > Updates and install any ending updates there because there may be a pending theme update.

Best Regards,
