A teacher wants to keep the "Course total" hidden (because it's not correct with her calculation method). The teacher went to Category and Items, scrolled to the bottom, clicked on the eye-icon of the Sum row to shut the eye, that row was then grayed out, and hidden from user report.
However, when the teacher unhide or edit a grade item (didn't even make changes, just hit save), the "Course Total" row automatically becomes visible. I tried setting "hidden until" and locking the sum row but that doesn't help.
Is this behavior expected or is it a bug? What's the reasoning behind un-hiding the course total automatically? Did I miss something to set it up correctly?
