"This series contains grades: remove or move them first."
Where: Grade system screen > a series > Remove the series. Owner only.
Why: only an empty series can be removed. This one still contains at least one grade, visible or in the trash.
What to do: move its grades to another series (Edit a grade > Series) or remove them (trash). A grade in the trash still counts: it is permanently deleted 30 days after it was moved to the trash; the series can be removed after that.
