After activating the free version of Hitman 2 AND the Legacy Pack (for owning the first Hitman), I was removed from Hitman 2 giveaways and SG says the game is already owned, so switching the giveaway to Standard Edition didn't really change much. I guess removing the Hitman 2 altogether would work, but it also shows that removing the first giveaway and creating a new one was unnecessary.
