Error description

• When a ClearCase label type with shared mastership is applied to
  multiple elements,
  and it is put onto versions on branches that are not locally
  mastered,
  and one of those versions is removed (rmver) at the site that
  masters its branch
   BEFORE the mklabel operation is imported
  then as well as (correctly) skipping that mklabel operation,
  syncreplica may also
  skip applying the same label type to versions of other elements,
  even though they still exist.
  
  
  Apart from the label not being available on versions where is
  should be,
   this can also cause a sumptom where a subsequent 'rmlabel'
  fails with the error
  
  multitool: Error: Can't delete 'REL_1.6.0' label on version
  '\main\1': label not found.
