Your PO4 coordinates are still in Angstrom. They should be nm for a .gro file.

I checked the docked structure and the structure obtained after
adding the ligand coordinates to the processed file obtained
after using pdb2gmx command. It's very surprising that in the
docked structure ligand is at the correct place but the
processed gromacs file the ligand lies far apart from the
protein. Any clue what could be the reason for this ??
If the docked structure is correct, and the one you reassembled is
incorrect, you made some mistake in putting it back together. It's
impossible to say what went wrong based on the (lack of) information
given.
