This happens all the time, and is not double jeopardy. Double jeopardy means you can't be tried in court by the same jurisdiction twice for the same offense. You weren't tried in court so it doesn't apply.
Mr. Cassara is absolutely correct. While it feels like the military just kept coming after you, it's above board.
That said, if you think your discharge wasn't justified or the categorization wasn't justified, you have the option to filing a request for upgrade through the Board Of Corrections of Military Records for your service branch. It's certainly something to consider if you are having issues with benefits. Many of the Military lawyers on Avvo can help with that type of work.

In the military you can be NJPd then courts martialed for the same offense; however, military cannot court martial then NJP you for the same offense. If you are NJPd the command can use that substantiated misconduct as a basis for your AdSep at a later date. If you want to look into upgrading your characterization of service you need to look into a Discharge Review Board. You can and should have counsel by a military attorney for the hearing.
I agree. These are two separate proceedings-administrative and criminal. Very often servicemembers are discharged after being convicted. You can petition the military board to upgrade your discharge.
