elliptical Intensity minutes not registering in connect app

Here is a screenshot of my heart rate from my elliptical workout on 12/19. I used a Polar H10, firmware watch 12.35, and registered zero-intensity minutes in the connect app. I should have accumulated 11 intensity minutes.

I accumulated intensity minutes on the peloton, and rower with firmware 12.35. I also looked at an older elliptical workout from 11/18, for which intensity minutes were recorded—firmware 12.22.

Is anyone else seeing this issue? Any suggestions or thoughts are appreciated.
