I created a custom field with a Tab setting, but when I go to Import the custom field is not visible as an option for importing. Custom fields that are inline are visible. Is this a limitation or a bug or something unique to my set-up?
Please check you have set your Fields to be Searchable. I think that if they are not Searchable, then they also do not show on Import. There is no difference, in terms of importing, between a Group of Fields that is set to Inline v one that is set to Tab.
