Jeff, I had the same problem. The groups are organized alphabetically. The way I got around it was renaming the groups a little.
My groups were originally: Guild Leader, Member, Officer, Recruit. I wanted Officer to be second, so I decided to rename it Guild Officer.
In your case, I would recommend renaming DM Enlisted to DM Member. Another option would be taking DM off the DM Enlisted. Not sure it will work for you, but that's the best advice I can recommend for that one. Sorry.
