Unlinking "Linked" audio clips

Some of my audio clips are "linked" (in Clip Properties it says "Clips Linked: (Multi)" as opposed to 0.  This probably happened because I started out this project recording multiple tracks simultaneously in "Comping" mode instead of "Sound on Sound".  I would like to unlink the smattering of linked clips from each other, but don't see how.  All the "unlink" menu options are shadowed out when I highlight the offending clips.  My recording method when I started this song was probably not "kosher"...and I want to see if I can save what I have done so far instead of starting over.  Reason: Sonar is becoming increasingly unstable as I record measures further down the line.
 
Craig Anderton, my hero,  said he always uses Sound on Sound to avoid issues (like this?) when doing simple recording.  I was doing multiple passes (looped) saved to separate tracks, and then dragging the tracks I like up to the the tracks already populated with previous kept parts of that instrument (guitar).  In "comping" mode, when recording "two tracks at a time", the clips end up linked.  Dragging some of them to other tracks, already populated with other, previously recorded clips, could be the reason I am now having stability (hang) problems with this particular project.  The tracks may be too "confused".
 
I may just start over...which is fine.  Or I could save clips individually and rebuild a new song with a fresh template.  I'm wondering what "artifacts" may be lingering in these clips...even if I save them to the desktop. 
 
I suspect that if I can just "Unlink" those linked clips it may cure the problem.  The were linked in comping mode, automatically.  Interesting.
