How do I restore grades that I can still see in Gradebook History to the active Gradebook?

Last night suddenly all of the grades I had recorded manually for Face to Face classes that are now remote disappeared from the Gradebook. I think they are still in Gradebook History. How do I undo this change? It happened a few hours after I entered some grades using Speed Grade.

Hi,  @lane_fletcher . I think you will need to restore the grades manually.
