Overdub not working on MPC One

For no obvious reason, overdub is not working on some tracks. The light flashes, but no note data appears. This happened after duplicating a track. What can I look at that could fix this? Thanks

For some reason, what fixed it was scrolling through the sequences on the main page - the recording icon flipped to red and now it works. No idea what's going on there, but in case someone else finds this useful, this fixed it for me.

Known bug, lots of strange goings on with the 'record arm' button.
