That must be due to one of these reasons:
- Correct filter/s is not applied. Please check to make sure correct filters are applied and they are applied correctly.
- Columns that is to be displayed in the report are not selected. Go to Columns section to select columns you want to include in the report.
- Incorrect usertype selected. Not all user has access to all data i.e. a usertype would only display data with which the usertype is associated with. For example, if you select reviewers usertype, it wont display data related to sessions as reviewers are not displayed/included in sessions.
- Incorrect Date range is set - If you select a date range, the report would only list data between those dates. So, make sure your dates are set correctly for the report you're generating.
