Strange VTK file output, not readable in Paraview

Unsure if this is a Paraview issue or a specfem3d issue.

I ran the example: check_absolute_amplitude_of_force_source_seismograms with 32 processors.

Output in DATABASES_MPI directory were 32 mesh VTK files.

Below is section of output from one of the VTK files.

Some rows only have 2 values instead of 3 (in other examples the VTK output rows have columns of x, y, z point coordinates. Are the two values just x, y ?

Also, Paraview or Mayavi does not recognize the * character, so the whole file fails to be read in.

Is this an issue on my end, possibly with the parameter files, or a bug? Thanks!
