Unlock all modes glitched

[Ecto_Cooler1987]

I think this trophy is glitched. I completed all challenges and unlocked all but one character (beat Grand Prix with all characters). I have all the game modes unlocked in my collection tab, but still the trophy won’t pop. There is a locked tab on the front page in the bottom middle of the screen. I have no idea what it is or how to unlock it. I have beaten MVP Hunter at least a dozen times. It’s truly unfortunate as this was a fun game and I wanted to add the platinum to my collection.
