live blackjack bonus counted side bets but not main hand somehow

I hit a live blackjack promo tonight and it only credited my side bet, not the main hand, which is a first for me. Always thought these bonuses went off your actual blackjack wager and not the sides. Dealer said nothing, it just auto-credited the smaller side win and skipped the main part entirely. Kind of confused if this is new or I missed some fine print somewhere. Never noticed them doing this before but maybe someone’s been keeping better tabs than I have. Wondering if anyone else here has seen that happen lately.
