One camo should work for both sides. They recently introduced online loadouts in battlelog so I doubt that it's a save file problem but you may never know..
I experienced this as well, I set up all the classes with camos online, went in game but all the classes that I played reverted back to the default camo. I changed them back to what I wanted in-game and it seems to have saved them for now..
Edit: Played a bit more, the camos haven't reset yet.
Edit2: Camo reset to default. ☹️
I'm not sure but I believe it reset after we finished a round and teams were swtiched.
I am having the same problem.
I set up camo, option 1 (which main weapon with which accessories) option 2 (which sidearm) options 3 and 4 and save them.
When I go to game, all of the options EXCEPT camo are saved and used ingame online. SO, I reset the camo to the one I want to use for each soldier class and play. It always reverts back to default camo though.
