Featured page slider not accessible in Homepage/frontpage

Hi First of all thanks for the job done, I think it is brilliant. I have a problem though: When I try to customize the featured slider (appearance -> customize -> featured slider), I only have the possibility to select my own pages when the slider option is set to "entire site". If I choose "Homepage/frontpage" in the drop-down list, then I can't change it (it stays with the demo featured slider) because there are no parameters available. Does it have to do with the free/pro version or something else? Same thing for the featured content set-up, if I choose "homepage/frontpage" then all options disappear and they reappear when I select "Entire site" fyi, I have wordpress 4.7 and catch base 2.9 (both are the latest versions available) thanks for your help
