Accidentally, I found the answer. I need to set the interpolate field between for and until fields. for instance:

instance:
Schedule:Compact,
  On,                      !- Name
  Any Number,              !- Schedule Type Limits Name
  Through: 12/31,          !- Field 1
  For: AllDays,            !- Field 2
  Interpolate: No,         !- Field 3
  Until: 24:00, 1;         !- Field 5
