I think they are OK, provided that at least one of Chock & Bates, Weaver & Poje, and Papadakis and Cizeron win another GP, because they should win the tie break based on high score with another team who has two silvers. They lose to any team either 2 golds, a silver and a gold, or a bronze and a gold.
