How to remove customized PA? I dont like Cherry Blossom Type 0 i just cant get the second slash to proc

There's suppose to be an item you can get from the swap shop that'll restore the PA to it's original state, but SEGA didn't add the menu that has said item. So I don't know what to tell ya. Maybe make a thread about it in in-game suggestions? Because that really needs to be in the game.
