Hi Dan,
I looked at your schedules.
In the Residents tab the popup shows that Dinah is on in September, but only until September 2. Looking at your Annual Rotations Schedule I see that she is indeed on Surgery from mid-August to September 2. (Your August block goes to September 2.) Starting September 3rd she is on Kaiser, and is no longer "on" the Call/Shift schedule.
The system will always allow you to remove somebody from a schedule that you added manually. But if they were added because they are on a Rotation, you must remove them from the Rotation or the Rotation from the Call/Shift schedule.
I hope that helps. Regards,
