draftkings blackjack replay skipped the card that made dealer 21.

So I ran the blackjack replay on DraftKings after a weird hand, and when the dealer ended up hitting 21, the replay just kind of skipped the draw where that last card should've come out. Dealer's upcard was a 6, then he showed a 5, then bam, another face card but the transition was instant, like the card just appeared. No smooth animation or pause like usual. I wasn't even betting big but it threw me off. Has anyone else seen replays glitch like that, or is my browser just trash? Trying to stay steady with my game analysis, but little stuff like this kills my confidence in the site.
