Multiple Letters for Same DQ Code

So my DS's DoDMERB portal shows multiple letters sent for the same single DQ Code (Hearing). Is it because they have IT issue or because he applied to multiple SA's and DoDMERB only sent DQ to applicable SA? Is the review done and that why they displayed a status of "Single" DQ. In order of preference, DS applied to USNA, USCGA, USAFA, and USMA. USFA notified him of the DQ and a waiver is under review. We are hoping that he failed the standards for two and passed for his first choice....
