In a recent game, I played a Warden of the Grove. It received a +1 token as normal at the end of my turn. On my next turn, I played a Traveling Chocobo, resulting in two triggers from Warden of the Grove. The first trigger offered me the option to put a +1 counter on {Card Name}, which seems like a bug. I selected that option, and it still correctly put a counter on Traveling Chocobo - it was only the display text that was broken. The second trigger correctly offered me the opportunity to put a +1 counter on Traveling Chocobo.
