Can't change the featured slider settings

Hi guys, I can't change the featured slider settings. According to the manual It should be done via the customizer, see: https://gyazo.com/915c878bde312a1fd9df613e624d2cbb source https://catchthemes.com/frequently-asked-questions/#question-customization-9 When I follow the instructions, I only see these options: https://gyazo.com/a06ce3e4b601e829fb81f4ec3baf3b9c Am I missing something or is this a premium feature? Thanks in advance! Best regards, Tim van Rooijen
