This is very strange.
As far as I know grompp and editconf (unless you use -pbc) do
not do anything to the pbc. And with the options you used
should not touch the coordinates at all and they gro files
should be identical (except maybe for generated velocities).
If you can easily give me access to the files I would like to
have a look at it.
But with trjconv you can use your gro file with -s to make
the -nojump option work as you want.
