blackjack promo says double downs count but progress only moved on regular wins.

Was grinding a blackjack bonus where the terms said double downs would count the same as normal bets, but when I checked my progress bar, only my straight wins bumped the percentage. Lost a couple doubles too and those didn’t help move it at all, so now I’m wondering if it’s just a sloppy promo or I missed something obvious in the small print. Seems like this could be a deliberate move, or maybe they’re tracking double downs differently and not explaining it well. Curious if anyone’s seen this or figured out a workaround.
