Minimum energy in Geant4-v11

In Geant4-v11, minimum energy could not be set.
I use Penelope or Livermore models.
I set the energy range by

G4ProductionCutsTable::GetProductionCutsTable()->SetEnergyRange(100 * eV, 1 * MeV);

But generated X-ray (Fluoro and Bremss.) is above 1 keV( it may be default ). In Geant4 10.7, its x-ray is above 100 eV in the same code.
Of course, I tried

/cuts/setLowEdge 100 eV

but I get the same situation.

Please tell me how to set the minimum energy less than1 keV in Geant4-V11.

Thanks.

Hello,

please, try out

emParameters->SetLowestElectronEnergy(10*eV);

or

/process/em/lowestElectronEnergy 10 eV
