AirPodPro3 HR function interfering with Watch Series 9 fitness monitoring?

I recently purchased AirPodPro3, to replace Airpod4 (ANC),and I have a watch series 9. noticed the watch was having issues with HR capture for fitness and rings. But when I activate the APP3 HR function it seems to totally kill watch a the ability to track calories or connect to fitness workouts etc. it now catches HR via health app via AirPod but loses everything from watch.
