Dear mauna,
1) You can reduce the R0 values for corresponding atom(s) in the
case.struct files to get rid of the R0 problem.
2) You need a lower energy cutoff to reduce the core leakage.

check also the RMT values, whether your RMT spheres are touching ?
touching spheres will not work in APW+lo method.

with regards
susanta
