Parlay leg settlement?

been running into a weird snag with parlay leg settlements and i can't figure if this is a one-off glitch or a common thing others see. had a 4-leg parlay, first leg lost early, but some time later the sportsbook marked two other legs as “void” due to some player prop changes before the game. they settled everything as a loss since my first leg died, but i got curious - what’s the real standard for how legs are treated if later legs void out after the parlay is dead anyway?

i mean, if a bet’s lost on the first leg, does it even matter how the rest is resolved? feels like it shouldn't, but in cases where you have disputes about voided legs or partial payouts i’m wondering if anyone’s ever actually got any movement from a book on that, or if it's just up to their own internal logic. anyone got examples where the parlay settlement changed because of what happened with voids after the fact?
