Hello NuWildcat62,
The free PDFs only come with items purchased through a subscription. You have a pawns subscription now, but it looks like you purchased the Age of Ashes Pawn Collection a little over a year before you started the subscription. That is why you don't see PDF for it on your account. I don't see the Bestiary Pawn Collections before Bestiary 3 on your order history at all, so it is possible you got those elsewhere. Those both also released before you had a subscription though.
