Allow to change/add birthday on My Procare - Review and Report - New Families Tab

When I did a filtering by age on My ProCare - My Procare - Review and Report - New Families Tab, I noticed that one child is not included there as his birthday wasn't mentioned on the main Tab. However, it is in his profile, so it looks like a bug. I wanted to change DoB by myself, however I'm not able to do it.
