Well the medals are all messed up but at least all obtainable. Berserk unlocks at 200 kills rather than 100 and yes despite unlocking it in-game you'll only unlock on-profile at 200 (and in-game it's a 200 medals kill medal that isn't even on-profile)
Novice and Guru are also reversed, with Guru awarding after completing 3 missions, and Novice awarding after completing 9.
Gladiator is also bugged, awarding after merely playing the Tank stage even if you lose. You don't have to beat the tank to get this medal or at least it awarded to me merely for getting to that stage and playing it one time even though I lost.
This game is really slow and grindy. It also experiences cumulative slowdown the longer it's running.
