I was plotting a DOS for one of my system,
and was interested to find the CHGdensity for the
frontier bands.

I am using a 4X4X1 (gamma centered) basis set and the system
has 1210 electron. I find the following occupation for the differeent k point in the PROCAR

band 605 # energy -2.54734499 # occ. 1.00000000

I am puzzled why there is no occupation on certain K points.
Further, again for the unoccupied bands i get the following,

band 606 # energy -2.47308479 # occ. 1.00000000
band 606 # energy -2.47431327 # occ. 1.00000000

Could any one let me what i am observing.
Does this make any sense.

I don't think I understand your question. The states are occupied if their energies are below the Fermi level, otherwise they are unoccupied. There is nothing strange with that.
