Recording MIDI in Cycle Mode...still hearing previous takes!

I do have that selected. In my transport panel, “MIDI Cycle Record Mode” is and has been set to “stacked”. It seems to be working in the “stacked (no mute)” mode though if I understand that mode properly. I keep hearing the last take that I just laid down, screwing with the take that I’m trying to record.

Is there something else I need to have set also, maybe something in Preferences?

Thanks!
