Most likely, you ran into approximate linear dependency and got
ghostbands in the occupied regions, so that EF dropped into the valence
bands.
It does not make sense to add RLOs for O-p

Dear All,
I have been performing calculations with GGA+U with spin-orbit on an Fe and
oxygen based material. I have noticed an unusual effect when using RLO's (
the relativistic local orbitals) for the oxygen p-states. I applied the +U
orbital potential only to the Fe ion and then applied
