There is a consensus rule in place for all picks of Streak Survivor. Unfortunately when one side is heavily chosen, the selection will become unavailable.
In your case, the selection became unavailable after having clicked on the game. It can however re-appear if users who have clicked on this game decide to select the other side or not make a pick.
Best of luck on your way to 25.
