Glitched Commedation

So I had started the Seabound Soul tall tale on one day and got to the first checkpoint. Nothing strange there but after logging out and coming back the next day to resume the tall tale I found that I had somehow gotten the Fire and Ash commendation (for getting all commendations) without ever doing anything resulting in having 3 commendations the first Fire and Ash and the reward for Fire and Ash. So I'm just confused on how this would happen.
