No. I won 6 of the largest size. But, I know that I had to win at least a few of the middle size and it shows I won zero. The photo on the mission is of the large one.
I will wait for Spirit Keep to open again. Maybe it was a one day glitch. If I have another problem I will contact support.
The smallest one is [affinity] potion, the middle one is Greater [affinity] potion, and the largest one is the superior [affinity potion]
As in anyother misaion, the picture in the banner is the reward that you will get once you finish the mission, so the superior potion in the picture is the reward you will get once you finished the mission, NOT the target.
I think we have solved this mystery.
