side bet voided again

Had another side bet on blackjack voided today, dealer just called supervisor over and poof, chips back in front of me. Not the first time - feels like any time I finally get a run on those side bets, something technical goes down. Doesn’t seem to happen when I brick, only when I’m getting the upper hand. Maybe that’s just the gambler in me talking, but it messes with my sense of stability.

Not sure what I could be missing on my end. My seat’s clear, bets are placed before the deal, not splashing chips around. Could they really be seeing something I don’t, or is it just protocol whenever they spot a possible camera error or shuffle mistake? Kind of throws off the table rhythm for everyone. Curious if folks here run into this or if I’m just unlucky lately.
