In some circumstances the end time selector on the edit_entry form can become blank. For example, in a system with a booking day running from 08:00 to 19:00 try and make a booking spanning more than one day, eg 5 Sep 10:00 to 6 Sep 11:00. Then change the end time selector to 09:00. The duration is now 23 hours. Then change the start time selector to 08:00 and the end time selector goes blank.
