Is there some errors with the actions in the Ms-Pacman dataset?

[hutchinsonian]

I downloaded $store$_action_ckpt.10.gz and $store$_observation_ckpt.10.gz in atari-replay-datasets/dqn/MsPacman/1/replay_logs. I found that action and observation do not match. Specifically, the first 10 actions are array([2, 2, 2, 2, 6, 2, 2, 7, 7, 7], dtype=int32). And I found that the action definition here is the same as https://gymnasium.farama.org/environments/atari/ms_pacman/ , action 2 controls the character to move to the right. I saved the first few frames of observation:

Why is the character moving upwards? Am I missing something? @agarwl @tangbotony @zhixuan-lin @google-admin
