cloned tracks open up linked in X3

In X1, I used to clone tracks and the new cloned track would be an independent entity I could do with as I so desired.  In X3, the clone is somehow linked to the original such that if I mute one track, the other mutes.  What?  Why would I clone a track if not that I wanted to do something different with it?
 
How do I clone a track and have a free, independent track?

it is an audio track, like a vocal or a guitar track.

I'm sorry, I have brain damage, been working on this since 5 am.  It happens when I clone a midi track.  I uncheck 'clone events' box and two new midi tracks appear (not one), and those are linked to the original (even though the 'link' box gets greyed out when you uncheck the 'clone events' box. 
 
How do I clone a midi performance track without it being linked (mute one, the other is unmuted)?

Nope.  There are no clips in the midi clone, so I can't unlink clips when there are none.  Here is exactly what I am doing:
 
1. select midi track #10 that has a grand piano performance on it [one big*ss clip beginning to end, because the lady can play flawlessly]
2.  right click on the blue highlighted #10 icon, and select clone track unchecking the events
3.  I get 2 new tracks, not one, neither of which has any events in it
4.  when I mute one track, all three get muted, thus I assume the two new tracks are linked
 
I don't want two new linked-to-the-original clones, I want one free unlinked clone.  Why is X3 doing this differently than X1?

Nope.  I'm using the smart tool.  If I click on the "track" in an area where there is no clip, or if I click at the top of the clip (where it says "Record 6"), at neither spot is there an option to Clone.  By your use of the term "header area" I assume that is the area left of the track area (track area being where the clips are) and the header area contains the M S RecordButton, track number, the effects bin, all the other in-out-track-control stuff.  If I right-click anywhere in what I believe is the "header area", I do get an option to clone the track, but in that case I get 2 new clones all linked to original.  In no other place do I get a right-click option to clone.  What am I missing?

It is an instrument track, not an audio track or a MIDI track but a hybrid of the two. Do not attempt to clone an instrument track, break the track out into separate audio and MIDI tracks by right-clicking on the track strip and selecting "Split Instrument Track". Then clone the MIDI track. Or just copy the MIDI data into a new track.

Yes an instrument track and it works the same way in X1.

As another alternative, you could also Ctrl+Shift+Drag the MIDI clip down to open space in the clips pane - that should create a new MIDI track with the clip at the same point in the timeline.
