They didn't void wagers on it, I suspect it was intentional, then it got hammered down which is how the consensus 22-23 you posted above came about.
I don't believe they choose what DB publishes as their opener, it's merely the first line their tracking software picked up, which is likely automated for MLB but may have required manual intervention for something like the Olympics
