Style arrays are already with array()
For me, the solution was to add a condition in edit_input.js
$(document).live(‘acf/setup_fields’, function(e, postbox){
$(postbox).find(‘.field[data-field_type=”font-awesome”], .sub_field[data-field_type=”font-awesome”]’).each(function(){
// Fix Bug
if($(this).parents(‘.repeater.empty’).length !== 0){
return;
}
initialize_field( $(this) );
});
});
