Cubase AI Key Editor: quantise not snapping to grid

Using the MIDI Key Editor, I’ve recently noticed that it’s begun snapping between quantise grid settings. For example as the attached snips show, the highlighted note C3 will snap either slightly ahead of beat 48.31 or, when I drag it to the right, slightly ahead of beat 48.32, never on the beat division. You will see also that the start of the note has been quantised to slightly before the start of beat 48.23. Quantisation is set to 1/16, note length 1/16. What am I doing wrong?


You have the Soft Quantize option enabled.

Thank you.
