I just tried, and as suspected, it is related to the tracks being set as audio tracks (the new default). I used the edit pulldown - extract channels to tracks.
Then enabled the channel table checkbox, and when I hit OK I got weird message saying track numbers had to be between 11-48 so I changed the track table.

Then when I hit OK I got flashing yellow message saying it did not extract to audio tracks.

So I changed the 16 chosen tracks to MIDI tracks and tried again; nothing.

I guess you broke it!
