Hi Pierre,
All Offered interactions should have a corresponding Answered, Abandoned or Flow-Out metric. If the interaction is not waiting on the queue and also doesn't have a Answered, Abandoned or Flow-Out metric, I would raise a case with care to check what has happened on those interactions and where the anomaly is.
