Why did this daily tournament start both of my games against the same opponent simultaneously?

I've been in this tournament since 2019:

Why did both of my games, playing as white and black, against andrewLLLL start at the same time when round 5 began? None of the other players started both games simultaneously. Both of my games are still ongoing, so hopefully, tech support can track back how this happened.

Was this a bug?
