Cant Deploy the project

I try to deploy and always recieve the following errpr message. "your form cannot be deployed because it contains errors:

The name column for the ‘ly8lc15’ choice list contains these duplicates: ‘_’. Duplicate names will be impossible to identify in analysis unless a previous value in a cascading select differentiates them. If this is intentional, you can set the allow_choice_duplicates setting to ‘yes’. Learn more:"
I Dont know how to find these errors? so I can deploy.

Welcome to the community, @asodangi! This post discussed previously should help you understand what is happening with your form:

You could also validate your XLSForm through this online validator to identify syntax issues causing deployment errors.
