I seem to have to do this for each reward. I have the last QSO that shows as confirmed in the detail but doesn't put me over the top on the statistics. I've posted here twice and both time the answer was that the updates are done when resources are available and it could take up to 24 hours. Both times, however, the award showed up within minutes of my post, so whether it's been a good luck charm or the catalyst for action I don't know, but I'm superstitious, so... I'm pretty sure I have 100 countries confirmed and the analysis only shows 99.
It should qualify towards 100 Award. If it doesn't show enter a customer support ticket at https://ssl.qrz.com/support
