Cascading select: error message allow_choices_duplicates

Hello guys, I’m new in this community. Please help me with my problem. I’m trying to use the function of cascading in kobotool but i’m recieving an error saying allow_choices_duplicates. then I search for the solution and found out about the xls format that shows the survey,choices, and settings. but how can I enable the settings without actually uploading the xls file?
