Set production cut in xml doesn't work

Hi,
The production cut in xml seems doesn't work. 
  <limits>
    <limitset name="dc_limits">
      <limit name="step_length_max" particles="*" value="0.5" unit="mm" />
      <cut particles="e-" value="100" unit="eV" />
      <cut particles="e+" value="0.01" unit="mm" />
  </limits>
