At present you have two options: Increase the Bi sphere, but at the same time REDUCE the Se sphere, so that there is no overlap.
Reduce the core-valence separation from -6 to -7 or so (check, which state produces the core leakage). Don't ignore a leakage of 0.023 electrons/atom. PS: In the next release there will be an option to overlap core densities which reach outside the sphere and then core leakage is not a problem anymore (but the required dstart step will cost some computer time).
