A DD-214 isn't always a prefect record of your service. In 1972 when I was discharged the personnel clerk handed me my DD-214. I looked it over and told him it didn't have everything on it and had some things that I hadn't done. He looked at me and said " do you want to get discharged today or would you like to stick around for a few more days while we correct it". I just wanted to get home so I said screw it.
Ditto. However I do have the original orders for the stuff that is missing from my 214.
