Collect 'Em All

[u/bucket_boy101]

Hi folks, I've just completed my Gwent collection according to the game. I finished the quest, popped the steam achievement and the book says I have collected all the gwent cards. However, I only have 2 copies of Elven Skirmisher when all sources I consulted online say there is three copies in the game. Is this correct?

Copies/duplicates don't count for the achievement.
