SEAOS date a month longer than my EAOS date?

Title gives the gist of it. I’m in the NAT program and I graduate A school on the 9th and was told that reservists normally just go home the day of graduation. However I was looking on my NSIPS and saw that my EAOS date was July 9th but my SEAOS date was August 9th, a month later. Is there any reason when this would be? So far student management said everything was fine but that was before I saw this on NSIPS. Should I bring this up or just dip then check into my NRC?

Any help would be greatly appreciated because this is so confusing
