Problems with “Featured content” and “Featured slider” in child theme

Hi I'm using catch-base-pro theme and want to make a child-theme to this. It gives some problems however. It is in the Appearance => Customize menu Here does neither the "Featured Content" nor the "Featured Slider" work. Both of these are marked with "Enable Featured ... on" = Homepage/Frontend" But there are no parameters to configure these settings. The parameters are ok when I switch back to the parent theme. I have tried this on clean new installation with Wordpress version 5.9 and Catch-Base-Pro version 4.4.1 Any ideas? Regards Laurids Petersen
