Game review one move behind on all moves?

For some reason my game review went behind one move for all moves, for example, my opponent made a blunder allowing a mate in 4, but on my move the move before he blundered, the eval of the game review changed. The coach said I blundered mate in 4, all coach explanations and evals are one move behind the board. I checked and this was for all moves of that specific review. I don't know why this happened, just wanted to know. Here is some screenshots: (Pay attention to coach, his explanations all seem to be one move ahead.

that's so weird, never happened to me before

I was wrong in the first post. It seems that the game review was running correctly until I played this move, Qe5 and this one specific move was omitted from the review. All other moves except this are present, causing the rest of the review to give messed-up coach explanations. Sorry for the incorrect info from before

Refreshing seemed to fix the issue, but I am curious if there is an explanation for the original bug

I've had that problem too!

We’ve seen intermittent reports of this but have never been able to reproduce, unfortunately. If you do find out what causes it please let us know!
