Divede Track List Error

the problem

  1. create MIDI track
  2. creat chord track
  3. create Arr track
  4. Then click 'Divide Track List"
  5. All gone

Still Happen from C 7.5 until 8.5 nothing Change

I think there’s an error …
an I Cannot Re-Open the project that divide track list active (saved) … but if I copy that project and open at another computer wuth cubase … it works fine … Already re-install my cubase but nothing change
