Garmin Coach Workouts and delayed speed recording.

Hi - Anyone else have this issue in a garmin coach workout during countdown between intervals it records speed at 0 for 45-60 seconds.  I can be in a run between interval 1 to interval 2 then it starts countdown and speed drops to 0 causing the next minute to be a constant too slow message, followed by too fast soon after.  This causes the data for that 10 or 20 minute interval to be incorrect.

example:  Never stopped jogging, however you can see in chart what I am referencing.  25 min mark to 26:20 no speed
