History not working

History is not being recorded in Rhino 8. My history settings are set to:
Record=Yes Update=No Lock=No BrokenHistoryWarning=No RecordAnnotationHistory=Yes

If I build a blend curve, move one of the ‘curves to blend’, then run HistoryUpdate, Rhino says there is no history and doesn’t update.

History works as expected if Update=Yes is turned on when I create the geometry.
