Duplicated Entries via Polar (w/Dif Calories)

Ever since I connected Polar Flow to track workout calories, two sets of data entries are entered into Cronometer -- e.g. one at 657cal and another world be much lower like 112cal.


The time and duration is correct/same for both and only the higher caloric entry aligns with Polar Flow's data.


Could this be a bug or a set up issue?


Thnx!
