Hello @M1chaelP
Several of us have raised this "bug" with the Fitbit team. There's currently a feature request to Allow exercise duration to display minutes and seconds (<-- click link) in the Product Feedback forum. You might want to add your vote & comments to this feature request.
Hopefully, we'll be able to see seconds again in our completed workouts in a future app update.
