Cascading questions - select multiple using media file (CSV file)

I want to develop multiple selections of division, district, upazila and union using cascading. I am keeping my CSV file (division, district, upazila and union) as attached file in media. But after selecting multiple names of division then the district name does not show.
When I put all division, district, upazila and union name in choices sheet in my form and write code in choice_filter, this system works. But I want to keep all my names in CSV file.
Here I am attaching my Excel and CSV files.
