I think this is a bug.
I played a game and made a dumb mistake in the end. So I lost the game. My opponent and I forked the game (Have fun) and played only the losing sequence new to see what the outcome would have been when I didn’t make the error.
As I read such game should not count. It doesn’t count in the ranking but in the statistics (see screenshot).
It should be only 4 out of 7.
I think that should not be.
Best regards Sipjin
