Rocket League Edition?

Question. I already downloaded Rocket league from the store when it was free, but now I want to buy an Ultimate Edition of Rocket league just I'm a bit worried because I don't know what will happen when I put the disc in my Ps4 because then I would have laid two rockets. Can someone help me there?

There's no longer an Ultimate Edition as the game is now free.

So just use the one from the store.
