Achievements are dropping first game played.

I have been playing some new formats to complete the MTG arena formats achievements. However I have played 10 games of alchemy only to be credited for 8 and 7 games of explorer but credited for 6

It seems to be dropping the first game of the day in each case as my first days alchemy was 3 wins/3 losses for 5 games and the second was 2 w/2l for an additional 3 games.
