Time waits for no Kang trophy

I’ve 100% Marvel Superheroes 2 with this trophy being the only one I need. I completed the story fully and then after that, I used cheat codes for the characters. I’ve done the races all over again to ensure I’m not missing them.

Does anyone have any idea how to get this trophy to pop? Should I be doing one of the levels again that’s associated with a cheat code character?? I’m confused because I completed the story before using any cheat codes.
