Commenting out the aparently ingorrect symmetry operators:

    loop_
        _symmetry_equiv_pos_as_xyz
        1-x,1-y,1-z

The spacegroup symbol seems to be correct, as judged by inspecing cell
packing in Encifer with the symmetry operators commented out and with
the space group H-M symbol in place.
