Hilton HHonors - QF=QN regarding to Hilton?

I was very surprised when I saw my folio for a stay in Philadelphia earlier this week. I did change my FF number to my new QF number(Yes I am going for the Concorde award). On my portfolia QF was listed as QN and when I mention that for the person working at check in they said everything was in order.

Can I expect miles to post on my account or will I have to retro claim?

They will post....I have been doing the same for some time now....QN is the correct code that Hilton uses.
