Hello @ayatabbas,
Could you, please, provide a screenshot/extract for the duplicate cases, esp. meta data (start, end, …) and all _system variables, e.g. _uuid, _submission_time etc.
Pay attention to exclude personal/sensible data, please.
- Do you have these duplicates also in XLSX download?
- What do you use for data entry? Collect (KoBo, ODK) or Enketo?
- Which Server?
- Have any of these cases been edited on server level after submission? With bulk edit?
- Have any of these cases been uploaded manually?
- Do these cases have special characteristics, e.g. same device/user, specific time slot, failed submission before, bulk edit?
As you can see with the search function, unfortunately the problem happens sometimes.
