C6 MIDI issue

Hi, guys,
I encountered a new C6 “feature” - it records MIDI, but no events display on the track (it looks as if I would record an empty track) and there is no play back as I play it after recording, but there is data recorded when I open the List Editor (nothing in Score Editor though…).
If I put in a drum MIDI track (groove) from NI Studio Drummer, everything is as it should be. The same if I open (previously made) MIDI file or Cubase Project.

Any clues?
