"This grade no longer exists: it may have been moved to the trash."

Where: Award a grade sheet (a student’s Progression screen), Add a stripe button, or Level field of a curriculum item.

Why: the chosen grade is no longer available: it is in the trash, its system or curriculum is in the trash, or it belongs to another curriculum’s system (an item’s level must be a grade of its own curriculum’s system).

What to do: reload the screen to get the current system, then choose an existing grade. The owner can restore a grade, a system or a curriculum from the Trash for 30 days; awards and levels come back with it.
