3. Issue: No clear method to change Marked Individual name from system assigned to know individual name, default values in date fields?

We have a new help page regarding Marked Individual management. I think I’ve got the answers you’re looking for.

Name changing: if you’re trying to change the default name, update the value next to the Default label. This does not impact that UUID in the database, which I think is what you’re concerned with?
Adding a new name allows you to provide another label (such as Nickname) and an associated value.

Dates: Those are not default values. Those are examples of the format that needs to be presented. There is no date associated with an individual unless a user enters one.

Does that answer your questions?

I will try out the new page - regarding Marked Individual management.
