Needs fixed – Age Counter and Reminder Review

Started entering family members, and it was working well, so I upgraded with the purchase. On a subsequent entry, I mistakenly entered the wrong year, so I clicked "edit" only to find the year can't be edited. The only option available was to delete the entry, and redo it. I wonder if this bugaboo is a developer oversite, or if it's intentional.
