How to get rid of the allow_choice_duplicates error in web form while developing the tool

Hi there,

After finishing developing a form, I then thought of making some responses to some questions mandatory. But after I did that, I am now not able to preview my form. And the allow_choice_duplicates error pops up. I also downloaded the xls version and removed all the duplicate values in the ‘choices sheet’ (list_name column) and reuploaded it as a new project. But still facing the same issue. I would really appreciate your support. Thank you
