Today, I installed the Sonic Forces DLC, which was the first DLC I ever downloaded. But there were two Sonic Forces icons. When I pressed on the DLC, they said I needed the original game. I retried with the Sonic Forces cartridge in the Switch, but it still didn't work! So I'm thinking that I have to buy the game again on the Eshop. Well, I know this is not what I'm supposed to do, but what do I have to do?
