Menstrual cycle tracking error - my wrist temperature has been plotted incorrectly on the graph. Dip plotted instead of a rise in temperature, messing up my ovulation estimate.

The automatic wrist temperature recorded on one day was 36.81 and has been plotted about 36.2 on the graph. Temperature rises happen after ovulation so by plotting a dip, the graph estimates that my ovulation happened on cycle day (CD) 18, which would be very late for me. If the graph was plotted correctly, I would have ovulated CD 14, which is far more likely. How can I edit the graph? Or sync the wrist temperature and graph again?
