No Transactions Listed: Membership 3 + Authorize.net

I am able to successfully transact subscriptions through the Authorize.net gateway and the member subscription on the "All Members" page shows "authroizenetaim" as the gateway but the transaction does not show in the "Authorize.net AIM transactions" report on the Payment Gateways page.
(...wp-admin/admin.php?page=membershipgateways&action=transactions&gateway=authorizenetaim).

Any ideas?
