^^He probably meant open carry...but I do not think any LEO is going to quibble over a date of birth, in fact most of them have access to a dB that shows your permit on their in-car computer if you have a CHL/CHP and many of them don't even want to see it (which is the only requirement you have to abide by).
They want to know all about you, instead. Where you're going, where the gun is, if it's loaded, if you'll be tricked into believing requests are demands, if you'll do something snarky to allow an arrest (their only goal) or a ticket.
So just 'be nice' and carry however you like, and perhaps keep a copy of your request for correction in your pocket.
Be safe and be good.
