If you want to clear the list of Import History, you can delete each entry on the import history by clicking the Delete button.
NOTE: The delete button will be shown for the Incomplete attempts of the data import only. And if you click, it will not delete any records from your system. Instead, it would only delete the entry from the list so you can clear all the incomplete history.
💡TOP TIP: If you're getting skipped error messages it would be good to check if these candidates already exist inside Vincere. They could be sitting in the 2nd step of the two-step Candidate deletion process. More info on this here. Simply clear out these Candidates from admin settings and you'll be able to proceed with the upload.
