Simultaneous concept2 an smartwatch logs

Hi, I’m recording my rowing sessins with the concept2 app. I’m also wearimg my smartwatch during the training sessions. In intervals.icu i see both logs occurring at the same time (as it should be).

I can’t understand if intervals.icu is double counying my training logs or is it able to understand that they occurr almost at the same time and it considers only oneof the two.
I don’t want to shut off one if the two monitorings during the training because i record other sports by the smartwatch and the Concept is more accurate on rowing compared with the smartwatch.
