There have been many changes between Geant4 versions 5 and 9, including improvements in the high precision neutron code. These may include a decrease in cross section for given isotopes, but in any case, the later versions of HP neutron should be considered more correct. You will not lose any particles in SteppingAction unless you specifically remove particles in that code, which is not a good idea in general. hElastic designates the use of a more general elastic scattering code that tries to take the best elastic scattering model in each energy range for each particle. Depending on the physics list used it could be G4UHadronElasticProcess or G4HadronElasticProcess. LElastic refers to the older GHEISHA-style elastic scattering model.
