Star Wars Battlefront Celebration Edition Content

I purchased the Star Wars battlefront 2 celebration edition, not the upgrade but the whole game, and since I have a child account had to do so on the main adult account of the PlayStation. Though I can play the normal game, when I go to log in on my child account, the one I play on, I don’t have the celebration edition, but the adult account does. Is there any way I can make it so that I have the content I bought, and not the adult? Or did I just waste an extra $27.25 to buy the content I can’t actually use? If so, is there a way I can refund the celebration edition to buy the normal edition? Please help!
