[Wien] valence energies

I know this topic was discussed previously, but I'm a little confused

I have a system containing Ge, Li and H atoms. In the case of Ge the cutoff energy is such that the 3d, 4s and 4p electrons are treated as valence electrons. Looking in the scf1 file I find

ATOMIC SPHERE DEPENDENT PARAMETERS FOR ATOM  Ge1       
          OVERALL ENERGY PARAMETER IS    0.3000
          OVERALL BASIS SET ON ATOM IS LAPW
          E( 2)=   -1.7550   E(BOTTOM)=   -1.950   E(TOP)=   -1.560
             APW+lo
          E( 2)=    0.3000
             LOCAL ORBITAL
          E( 0)=    0.3000
             APW+lo
          E( 1)=    0.3000
             APW+lo

if the 3d electrons have an energy of -1.7550, where are the energies for the 4s and 4p electrons. Also where is the split of the 3d electrons. 

With the chosen cutoff energy, analysis in w2web is reporting 0 ryd for all H and Li atoms, and in the scf1 file for H

          ATOMIC SPHERE DEPENDENT PARAMETERS FOR ATOM  H 1       
          OVERALL ENERGY PARAMETER IS    0.3000
          OVERALL BASIS SET ON ATOM IS LAPW
          E( 0)=    0.3000
             APW+lo

so where do I find the 1S energies

Li is similar 0 ryd for core and

          ATOMIC SPHERE DEPENDENT PARAMETERS FOR ATOM  Li1       
          OVERALL ENERGY PARAMETER IS    0.3000
          OVERALL BASIS SET ON ATOM IS LAPW
          E( 0)=    0.3000
             APW+lo
          E( 0)=   -3.5225   E(BOTTOM)=   -3.720   E(TOP)=   -3.325
             LOCAL ORBITAL

for valence. Could someone explain this. I want to do core-level calculations on the 3d Ge electrons and I'm guessing that treating these as core would be incorrect as the energies are so high.

Thanks 

Michael
