Beat Adamantoise for the 3rd time. Still no trophy...

This is beyond frustrating. I beat it twice on 1 save. Then even did a New Game+ and beat it. Still nothing. Anyone have this problem and solved it? Everything else is unlocking. I have a save from before the battle and a save for right before I turn in the hunt. Didn't use a summon in the battle. Trophies are synced.

That sucks- all the time put into the game haha and nothing
