I can't buy games with EA Play

I recently subscribed to EA play so that I could try out the Sims 3 before purchasing, and I've now decided that I would like to buy it. However, there is no option for me to purchase the game because it says I already own it with EA play. I cancelled my subscription and the game still launched after it expired, but Late Night did not work. The EA app said I already owned late night but I couldn't use it and I couldn't buy it. I tried uninstalling everything to no avail. Is there any way to buy this game and late night or do I just have to keep giving EA money every month??? I really don't wanna do that since I ONLY use the subscription for this one game.
