Invisible cards?

I created a bunch of cards as a loot table for a chest that PCs can open. I can deal the cards out just fine, but when I click to view the cards, the player's hand opens up just fine but the cards aren't visible . Am I doing something wrong? I've only been able to test this on my own, do I need to have players in the game for this to work? Or do I need to have both card backs & card faces defined?

You probably need both sides defined. I dont have time to test this out now but I will do so later this evening (assuming you haven't done so already).  - Gauss
