Error in XLSForm upload

your form cannot be deployed because it contains errors:

Unexpected KoBoCAT error 400: b’{“detail”:“The name column for the 'group' choice list contains these duplicates: 'songtaabodib', 'wontaar', 'nyognye', 'tietaa', 'songtaa', 'nimonanga', 'akanweri'. 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: XLSForm.org”}’

@vibrantfield, I would advise you to validate your XLSForm through this online validator before deploying. The online validator should help you identify syntax issues if any within your XLSForm.
