[Paraview] Two issues with time-dependent data

Can you just set the upper end of the TIME_RANGE to one timestep
before what you have now? In other words, instead of having the first
and last timesteps provide the same data, end the TIME_RANGE earlier
by one timestep. That will prevent the doubling of the timestep when
the animation resets.

I'm not sure about this one. Maybe someone else can chime in.

Thanks,
