Doubling HR

I have my vivosmart paired to a ant+ heart rate monitor. Since the most recent update, it seems my resting heart rate has doubled. Also, my workout heart rate is much higher. E.g. Before the update, my bike ride to work was an avg of 110bpm and max of 140bpm. Today, the avg was 155bpm and max was 210bpm.

Help?
