Birthday Field settings

I am using the latest version of Blackfyre , but have this issue:

I like to set people their Birthdays, so i setup a extra field (see extended_fields.jpg in attach)

This field is viewable also on the register page for new people (see register.jpg in attach)

But in the profile in settings, i dont know wat this field is related too and why i cant see my own birthday field? (settings.jpg)
