If you're making a Game that's a copy based on an existing Game, the copy will keep all relevant sheet template information to match the original. The Sheet Template can be changed after game creation form the Game Settings-page. When starting a new game, you (as the game's Creator) have the option to choose the Character Sheet Template you want to use from the handy drop-down available on the New Game creation screen.
