Calorie Double Counting

Are you recording this activity on the Peloton and your Forerunner 165, and then syncing it to Connect? This could be why it is double counting the calories since it is recognizing it as two activities being recorded by different devices. 

I did do this, however the watch recording is deleted so I only have 1 activity on my account associated with the ride. For a sanity check I did a ride without recording it in my watch, instead just using it as a HRM and sending the data to the Peloton. The result was the same, with the calories being double counted despite there never being 2 activities. I have seen people reporting this is occurring with Zwift too.
