Recovery contact email

Just got an email (that is legit) from Apple saying that a recovery contact was added to my account. My recovery contact was set up a while ago, nothing changed in the meantime. Looked in my account, all seems ok, just one contact.

Was this a glitch, should I not worry? I remember that when setting up the contact recovery it said that I added it something like 1970 - it was an odd date and I read that that was a glitch.

maybe now this email just corrected things?
