The rotation and translation invalidates the previously calculated
energies for all images.

The energies won't be plotted unless *all* images have energies.  The
energies are calculated for intermediate images during NEB, but not
initial and final images, since those don't move.

Therefore: Most likely you just need to recalculate them manually for
initial and final image and they should all show up.
