Error: There does not seem to be a `allow_choice_duplicates` column header defined in your settings sheet. You must have set `allow_choice_duplicates` setting in your settings sheet to have duplicate choice list names in your choices sheet.

I can not generate to XML from by using XLSForm  
Could you tell why?
