There seems to be a problem with age field.
It
display erratic year (copyed from one account) , some have what they actually have in CP some don't.
I have updated my year in my CP and then most of them receive the same year in birthdate. I delete the year in my account and most of the accounts reverted to that odd year.
For the moment most of us have 1979. Maybe it was a good year
Any idea where I should look? I will test more to see if I can understand more of what is happening.
I mention I have a custom field with pull down menu displayed in postbit not in Staff page.
