How to edit submissions

Thank you for the restoring the fields.  However, today at 3:21pm eastern, one of the sub-users on my account attempted to edit Nicole Gould's registration and after she clicked Edit, the Arrival and Departure dates disappeared.  Should we Edit in a different way to prevent this?

I checked a few of your submissions and was unable to reproduce this on my end.  The arrival and departure dates remained intact when editing the submissions.  Is this still occurring?  As far as I can tell, it no longer should be.
