stake blackjack replay shows my double down card but payout still says single bet win.

I was going back through a blackjack session replay and noticed something weird - on one hand, I doubled down on a soft 15, the replay shows the double down card being dealt like it should, but the payout at the end is exactly what you get for a standard win, not a double. The chips get pushed out like it's just a regular win, nothing extra for the double. Everything else in the hand looks correct, animations, deal, even dealer behavior.

Is this just a glitch in the replay software or should I be worried my double didn't actually get registered? Anyone ever have this happen before and did it get resolved, or is this a sign to dig deeper into my past results?
