Missing Trophies after completing campaign on ACE difficulty.

I completed the game on ace difficulty, i watched the credits all the way through l, I returned to the menu and had unlocked the ship skins for the story rewards but I have not received the four trophies you get for completing this level of campaign, I have left my story mode in ace mode as I don’t want to complete the game again, as took a while on ace mode! Please help!
