The bonuses on the left side of the payoffs screen are additive. That is, if you get an Ace & Jack of Spades, you will get paid any bonus specified for AJ Spades & AJ Black & AJ Suited & Suited BJ & Spades BJ and the payoff for BJ. If you are simming 4:2 for AJ Spades and 2:2 for all other blackjacks, set the BJ payoff to 2:2 and AJ Spades bonus to 2:2. Don't set any other BJ bonuses. Also, if you have six card unbusted pays 2:2 and six card 21 pays 4:2, you will get both bonuses on a six card 21 in addition to the payoff for the hand. This is stated in the documentation, but with my usual brevity. I'll change the manual to emphasize the additive nature.
