The simulation has given you CONFOUT.GRO with new [good] density. I
guess this is the only output file you really need here. If you want a
detailed trajectory, please just use:
nstxout = something
nstvout = something
nstfout = something
nstxtcout = something
You may also use g_energy to look at the evolution of the PE density,
As for the pbc option, this is just an erratum. You are right.
