Game Review

My guess is that the "Engine Evaluation" switch would turn on/off the computer evaluation for games you're observing. If that's true, this switch does not seem to be functional.
There is an "Evaluation" switch to the right of the live chessboard which does turn the computer evaluation on/off.
Can Game review be disabled? It comes on after the game and i cannot start a new game nor offer a rematch. It seems like it is forcing a review.
