Orange theory

When I workout with orange theory heart rate monitor, it doesn’t transfer the Heartrate data to my Apple Watch, it just recognizes that I did an orange theory workout. I also tried to start a workout on my watch and orange theory at the same time, and it does transfer the heartrate data over, but it counts it as two separate workouts which double my calories on the watch even thought it’s happening at the same time. How do I fix this issue without having to double my calories burned?
