Priscilla. The gwent card is not given away. (The Witcher 3: Wild Hunt)

In the quest where we are going to save the buttercup, you can play with Priscilla in gwent (choice in the dialogue in yellow, like playing on a unique card), but at the end of the game she does not give a card. Is this how it should be or is it a bug? If a bug, what card does it give?
