Metallic Star Locations

I understand that metallic stars do not congregate in the center of the
galaxies, but this does not make a lot of sense to me. Why should this be
so? Don't the stars in the central bulge undergo Nucleosynthesis as do
others?

Also, why don't elliptic galaxies have metallic stars?
