Hello,
1) Issue with the EL version of your site was related to your translation. You have translated option key instead of the Menu title. We removed broken translation. Check now.
2) 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.
Regards
