In general, you need to play all Treasures before buying a card, because you can't play them afterwards. (unless Villa or other edge cases)
So you need to first play all Charms and select how often you want to gain a copy. Then you buy the first card (e.g. Gold) and the game engine asks you which copies to get. You click at them one after the other. In your example: buy Gold, click on Nobles, click on Nobles again.
