Garmin coach 5K plan workout sync issue

Hi,

Instinct is great to track runs, and coach is the right tool to get the training. I am trying to do workouts using the Garmin Coach in Connect app. Currently following the 5K plan. Benchmark Run synced fine, Walk/Run workouts are syncing but, the lap timings are not right. 

Can you please suggest how to copy the right workout on the Instinct?

Thanks
