If a game is discontinued on Apple Arcade, I can't get the achievements, bit the game is still listed as incomplete in my list of games with achievements. I have deleted the game, and I cannot re-download it.

If a game is discontinued on Apple Arcade, I can't get the achievements, bit the game is still listed as incomplete in my list of games with achievements in Game Center. So slowly, a part of my list of games in game center will be with achievements that are not possible to get when the games leave AA. how do I remove it? I asked the game developer first and they referred to Apple Arcade.
