What about this logic..
Since they are approving July cases already,they want to show some reason for the waiting April,May cases.So they post a RFE but don\'t send them to the Parties,they post that the replies were received..and approve these cases.
Or It may be that they have to issue certain no of RFE\'s per month,and that since they want to cut down the processing time to 6 Months,they post these RFE\'s themselves and approve...
Just my thoughts...
