when scheduled for Speed Repeats from Garmin coach, my watch do not do the Repeat part of the scheduled workout?

I am using the Garmin Coaching option.. which is schedules me for Speed Repeats.  But when I activatied it on my watch to do, start running... warm up, 1st repeat.. 1st recover...  workout cool down...  WAIT???? what happen to the other 5 repeats???  what am i doing wrong?   I am not touching any buttons, letting the watch tell me what to do next like any other run.
