When you need to edit an existing note that belongs to a Deal, it requires you to add again the day and time.
When you edit, the day and time get reseted and you need to stop editing, check what that information was to be able to add the same one and then save. That implies additional work and time doing something that should be very easy and fast.
The expected behavior is to be able to modify something and save without having to define again the same information.
