Hello, Modestino Ferraro,
Thank you for purchasing our theme and for contacting us.
Parent theme does not inherit child theme options. So, once you switch from child to parent you get other settings. If you want to import child setting to parent you need to go to Theme Options > Import/Export > export child theme settings, then switch to parent theme and import settings.
It is recommended to use the child theme. Read more – https://developer.wordpress.org/themes/advanced-topics/child-themes/
Kind Regards,
