fanduel roulette showed win animation then balance updated lower than payout said

Saw something really weird during my last roulette session. Ball landed exactly where I had a bet, the win animation played and even flashed up the right payout on the screen. But then my account balance only went up by a lot less than what the payout was supposed to be. Like, the visual said one thing, but the actual credited amount was off. Checked my bet slip and everything and it should've been a standard win.

Noticed the game was a bit laggy too, which always makes me nervous. I get that sometimes these games glitch a little, but I've never had it show a full win and then short me on the payout. I even reloaded the page but nothing changed. Just curious if anyone else ran into this or if I'm losing my mind.
