all that is normal behavior i'm afraid: as a matter of fact, a MIDI clip must have at least one note event to let it be seen on the main track view.
EDIT: scrap that, that is simply not true: you can have MIDI clips with non-note data alright. though they are shown just blank or empty on the main track view. however, the behavior you report, on the null-length and emptyness of the new clip is quite strange, as i just tried to reproduce and it just makes it wide enough to accomodate all the CC events in it (but show as a blank clip).
