fanduel roulette promo counted straight bets but ignored corner bets somehow.

So I noticed something weird during this roulette promo. The promo T&Cs said any bet on roulette tables would count, but when I checked my play log afterward, only my straight up number bets were registered toward the promo requirements. I mixed it up with corners, splits, and the usual spread but the corners especially just didn’t seem to trigger any progress. Straight bets popped up instantly but for some reason, it’s like the system skipped over anything not single numbers.

I triple-checked to see if there was some technicality I missed, but the wording looked clear - no mention of only straight bets qualifying. Kind of frustrating when you plan out your stake sizes for a promo and then your play doesn’t even register. Has anyone else run into this with roulette promos? Could this be some system thing, or do they just quietly favor certain bet types?
