At first I thought I missed something, then I realize the achievement got glitched.
I moved my old save file on backup memory stick and started the game with a new file. I had to redo all of the Situation Battle scenarios for it to finally unlock.
FYI, I ran through all Situation Battle scenarios in one go, without touching Arcade, Multiplayer etc.
I had the same issue; it didn't pop the first time, did everything in one sitting and it worked. Thanks for the tip.
