I don’t see where ‘mb_hairstyle_tabs_repeater’ is part of a layout. How are are you including the repeater in a layout? clone? What are the clone settings?
I have looked several times and I don’t see why the values would not be shown, unless the values to not exist. Can you confirm that the values are actually being saved in the database? After you edit the page where this is located are the values loaded into the fields to edit?
