Bet builder rejected

tried putting together a wild same-game parlay last night, not even anything too crazy, just some stats for nba rebounds, assists, and total points. builder let me build it, showed the odds, but then as soon as i hit confirm - boom, "bet not accepted". tried again, mixed up the legs a bit, same outcome. not the first time this has happened either, but never on something so basic.

i get it when i’m stacking eight legs with some funky props but this was like a grocery list. anyone else getting the rug pulled after thinking you’ve got it all set? starting to feel like their filters are set tighter than they admit. respect to models but why tease the combo if it’s never actually bookable?
