How do I turn off "new gradebook"

I made the mistake of turning on the "new gradebook" feature for my course.  Now my TA can't enter grades.

I can't find any way to turn the "new gradebook" off again.  (It looked like a toggle before I turned it on, but the toggle disappeared.)

 

How do I return to functionality?

 

This is my first quarter using Canvas, and it may be my last one.  If it continues to be so lacking in features and so buggy, I'm going back to hardcopy paper grading and gradebooks.
