• Closed as program error.

Error description

• When running File Manager Compare Load Module (CLM) function
  multiple times within the same jobstep, field values in the
  'Comparison summary' of the second and subsequent compares
  are incorrect.
  For example, when running the same compare twice in the same
  jobstep, the second Comparison summary will contain different
  field values than for the first compare.
  Also, when running multiple different compares in a jobstep,
  the second and subsequent compares show different Comparison
  summary values than if the second and subsequent compares
  are run as the only compare in a jobstep.
  This behavior is also received when using the FM Plug-in
  Compare Wizard for load modules.
  
  Example of same compare run twice within same jobstep:
  //STEP1    EXEC PGM=FILEMGR,REGION=1M
  ...
  //SYSIN DD *
