Task tickets allow you to set due dates, whereas incident tickets don't have due dates, you can set review dates instead.
However, if you convert a Task ticket with a due date still showing to an Incident ticket. when you then click into the incident ticket there is no due date showing anywhere. But if you go back one level to list of Issues in the 'triage' queue, the due date shows against the entry line for the ticket. If this is in the past and the ticket is still open, we are unable to remove it from the queue.
You can click on the due date in the issue area and cannot see how you can remove it?
