It's always the "added" cell record at index -1.
I/we may have a [for 0 to Pred(Count)] where we need a [for Low to High]
Also that is only a display issue as this record is not written to disk. 
Reloading the plugin "fixes" it.

The only concern is plugin's integrity. If everything is ok, then it is not a 
serious issue.

Best practice is to close and save after Add masters or Sort masters. Maybe 
that's why :)

I think this also impacts AddMasterIfMissing for scripts. When I use that the 
new masters are not inserted at the end of the list and thus cause existing 
references to break.

Use AddRequiredElementMasters(), always works for me.
