Coaching those that don’t need coaching

Brooke, I’m the in house coach at my company. These past few weeks I’ve been doing goal setting coaching sessions with the whole company. First few weeks were great – everyone that booked in then was switched on, into coaching, wanting to work on stuff.
Then this week it’s been tough. I’ve had people in my sessions who have come in because their manager has told them to so they don’t open up as much in the sessions as the other people have. Some of them have a very good view of goals and going about it excellently themselves. I still want to give them value, but when there’s not much to do on goals, and they don’t have a problem per se, what do I do then?
It’s their first coaching experience, so I want them to come away with some value, but when there’s no problem to work on, what would you say to do.
