player rebounds prop got corrected next day but my parlay payout never changed

Had a little something weird happen with my last NBA parlay. Threw a player rebounds over into my ticket, everything looked solid, won the rest of it and the prop was listed as a win right after the game. Next morning, I check my balance expecting the payout, but nothing moved. Checked the slip and suddenly the prop line dropped by one and switched to a loss. Total bummer, but I get that mistakes happen with stat corrections.

Here's my thing though - shouldn’t the payout update or at least give me a heads up if they change a prop result like that? The slip still shows the old payout like it never happened but my money sure doesn't. Trying to stay level about it but this is the first time I’ve seen them change a bet outcome after posting results. Curious how often this sort of thing happens and what folks do about it.
