It may just be the My Subscriptions page being buggy still, and if so I'm sorry.
After checking the My Subscriptions page it properly shows last month's fulfillment of my Adventure Path and Campaign Setting subscription, but it shows my next item as being for next month (Giantslayer and Belkzen), skipping over Divinity Drive and the Iron Gods Map Folio for this month.
I didn't see an order for it under my account either, so I'm not sure if I should worry about it yet.
