Sleep Insights orange bar missing

So I've had the Garmin Fenix 6 Pro for 4 days now and I was just navigation through Garmin Connect (GC) to check out the different types of data.

I came across Insights which basically shows how you compare to other people in your demographic. For steps and floors, I see an orange bar on the graph, but I don't see one for sleep even though I have 3 nights worth of sleep logged already.

I've read other users have had this issue. Is it a known bug? I wonder if Garmin is aware of this.
