patchsets.sh option available=metalink

Hello,
when running patchsets.sh to determine the latest patchsets to apply

I used the command patchsets.sh available=metalink

as per the documentation this option is supposed to restrict to only available patches on Metalink
---------------------------
Note2: (as of v.4.14)
  Latest Available shows all patchsets even if NOT AVAILABLE for download on
  Metalink. An optional flag to limit Latest Available to patches only available
  on metailink has been provided. ie. Add: available=metalink to command line.
 
  New Status Field:
  ##############################################################################
  PATCHSET STATUS:
