Can an incorrect training notation be corrected years later in my training record?

I joined the Army National Guard almost 6 years ago signing a contract as an 09S, officer candidate. I was not sure about becoming an officer with no enlisted experience although my recruiter convinced me it would not be an issue. Fast forward to attending Phase 0 of OCS at which point I realized I wanted enlisted experience under my belt before considering the officer route. When I notified my chain of command, the officer who ran the OCS program was not pleased with my decision and verbally expressed it to me. I left the OCS phase 0 program in good standing having passed all requirements including my APFT. I went on to become a 12B and upon arriving at 12B OSUT to be reinserted into BCT until AIT began I was berated by the Drill Sergeants and continuously referred to as an OCS failure. I ignored it all and charged on successfully passing 12B AIT. A few years later I was going through a records review and was shown my training record to which it has me listed as a PT failure and having been released from the OCS program. This is far from the truth. When I brought it to the attention of my chain of command I was told it does not matter. To me it does, it is a blemish on my record and I believe just as in AIT that I am unfairly judged on that blemish which I did not deserve. How can I go about having that corrected when nobody seems to think it matters? Would they have access to my PT records from the Phase 0 process to see that I did not fail my APFT during Phase 0? I am interested in attending OCS now that I have some excellent enlisted experience under my belt but feel that I am being unfairly judged based upon this incorrect information in my file. Thank you very much for taking the time to read this.
