FYI, online travel agencies (Expedia, Travelocity, Priceline, etc) typically get a pretty big cut on the room rates, so hotels view guests booking thru those channels as much less desirable than guests booking directly with the hotel. That would be my guess why as to why Expedia reservations would be cancelled first.
Regarding those reservations that have been cancelled, I would expect any payment to be automatically refunded to your credit card.
