Unable to create questions with external csv file

This is a known issue @vicks88! And, it has already been recorded in GitHub here:

However, it should not affect your data collection process, and you could carry on with the select_one_from_file question type for your survey project.

Note:

  • You should not edit your survey project through the form builder UI when you have the select_one_from_file question type. If you wish to edit, you should edit the same through an xlsform.
  • When you have the select_one_from_file question type, you may not be able to download your data in the XLS version. In this case, you will have to download the same in XLS (legacy) version.
