Training Plan not recognising completed workout

Seems to be a few of these questions, however no solution from Garmin. I did a workout in my plan last week and when reviewing the schedule, its not showing as complete. I had to complete the self-evaluation after doing the effort, therefore it was done! Is there a way to manually mark as complete or refresh the activity so it matches?

I stumble across this feature on Garmin and thought I'd give it s try. My OCD brain is not liking this and I'm about to remove the plan and go back to Intervals.icu. Such a nice idea, just a pity the functionality doesn't seen to quiet work.
