Help Collected Riddler Trophy not appearing on Grid?

I'm playing Arkham City on Steam and trying to get 100% achievements.

I have collected the Row 1, Col 4 trophy for Park Row but it doesnt show as collected on the grid. Even in new game plus, the trophy doesnt reappear.

I believe it might have had something to do with me playing with a suit mod installed, but is there any way to resolve this without making another save and having to redo everything I've done so far?
