I'm not sure what paraview plots in this case, but you can plot a discontinuous solution by using write_discontinuous_exodusII, for example. If I recall correctly, that will create a new mesh with disconnected elements so that paraview will correctly plot it as discontinuous. The downside of this is the mesh no longer matches the mesh that you solved on (since the elements are disconnected) but that may be fine in your case.
