Discrepancy in the magnetic moment from SIESTA and VASP

Hi, I have calculated the magnetic moment of VS_{2} structure in VASP and SIESTA and found the magnetic moment ~0.58 and 1.09 per formula unit respectively. I have used GGA-PBE functional, and for siesta DZP basis set for both V and S.

I have first optimized my unit cell (both Cell and ions together) in VASP, and compared the optimized parameters with other reports, structural optimization is fine. Then I performed Single Point in VASP and SIESTA using this well-optimized geometry. but I am getting quite different magnetic moments. Can anyone suggest a possible reason for this?
I have already tried to use different initial spin configurations. Even constraining total spin to ~0.58 and then reading this conversed .DM.
