Erro of init_bulk: WARNING : in directory XXX/POSCAR.02x02x02/02.md/sys-0008-0008-0024 nforce in OUTCAR is not equal to settings in INCAR

When I produce initial data for model trainling. I perform the init_bulk, but there is an erro:
RuntimeError: MD dir: XXX/POSCAR.02x02x02/02.md: find no valid outcar in sys sys-0008-0008-0024, check if your vasp md simulation is correctly done
And I look for the file 'dpgen.log'. There is warnning information:
WARNING : in directory XXX/POSCAR.02x02x02/02.md/sys-0008-0008-0024 nforce in OUTCAR is not equal to settings in INCAR

I wonder why this erro appears. I've followed the tourial to keep 'md_nsteps' and 'NSW' in agreement.

Following is my param.json:

1. {

2. "stages" : [1,2,3,4],
   

3. "elements": ["K","Ta","O"],
