Treadmill calibration not reflected in Intervals

Hi,

I have just completed a running activity on a treadmill and was able to calibrate the run on my Venu 3 to reflect actual distance run (there was a discrepancy between the distance shown on my Venu 3 and the distance shown on the treadmill). However when I look at activity in my Garmin Training Plan I see that the Intervals have not been updated with the  correct distance and correct average pace, and my Garmin coach is not happy because it looks to him that I have been running too slowly :-)

Is there a way to fix this?

Thanks,
