Garmin coach ignoring some successfully completed workouts?

This week, Coach planned workouts Mon-Thursday each day, long ride Saturday .

I've completed successfully all three so far. But coach has deleted Mondays and Wednesdays from the plan and called them rest days. It puts a tick beside Tuesdays (it still lists monday and wednesdays, but no tick). Edge 840 using an adaptive plan, but I wouldn't think it would adapt to remove existing completed workouts? The power output on my Kickr was controlled by the edge on both workouts, 99% completion success on both so its not removing them as not being completed correctly...

Any ideas whats going on?
