Do Fermi energy depend on NBANDS？

[wenkai_zhao]

Hello:
for vasp 5.4.4, i find the fermi erergy in static scf depends on NBANDS. my system is vdw MoS2 and WSe2, (ismear=-5, encut=500, ediff=-6, kpoint:15*15*1) here are the test results:
**************************************************
NBANDS Fermi
40 -1.995935
48 -1.87415
80 -1.886006
120 -1.875578
************************************************
However, for vasp6.1,( same incar poscar potcar kpoints with vasp 5.44) the Fermi energy is independent with NBANDs, here are the results:
**********************************************
NBANDS Fermi
40 -2.0664
80 -2.0665
120 -2.0664
*****************************************
is that bug?

Thanks
