Garmin coach race prediction not updating

Question

Garmin coach stopped updating my projected race time a while ago, also happens on the connect web interface. It is updating the estimated times in the watch in running performance though.

3368695 Can you clear all events on both the device and Connect, then re‑add ONLY the primary event, the device will regenerate the last 4 weeks of data. Maintaining a single event on the device prevents the erratic race predictor behavior. 
 If you are in the middle of a training plan tied to the event, deleting it will delete the training plan. **
