Can’t start second planned workout on the same day (Fenix 7)

When I schedule two workouts on the same day in Garmin Connect calendar, my watch only lets me choose between them before the first workout.
After completing the morning session, the second planned workout disappears from “Today’s Workouts,” so I can’t start it later in the day.

Is this a known issue? Is there a quick fix for this?
It would be great if multiple planned workouts on the same day remained selectable until all are completed.
