Large numbers in the output of voronoi/atom occupation

Hi all:

When I use the command: compute 1 all voronoi/atom occupation, I get very large number of the occupations like this:
4005 1 28.5721 24.6568 19.6988 1.74533e+07 2
4006 1 16.1782 29.0215 34.2943 0 2
4007 1 26.6656 12.3828 15.4321 1.75695e+07 2
4008 1 0.702219 6.15419 15.3856 0 2
4009 1 29.9978 26.4226 19.2562 0 2
4010 1 19.0529 20.7435 7.05381 0 2
4011 1 10.4844 7.46817 9.03348 0 2
4012 1 21.0488 2.33835 0.101724 0 2
4013 1 26.6171 12.219 13.1767 48 2
4014 1 0.689011 5.05151 17.792 0 2
4015 1 31.3881 28.2242 18.8385 65552 2
In this case, I just randomly create atoms in the cell and then test this command. Is it a bug or this command can not be used when the atom number changes? I used the latest version of lammps.Thanks.
