Why does SimRF give wrong results with impedance mismatch?

I take a modified example from SimRF:
model_ce = 'simrf_xline_ce';
load_system(model_ce)
open_system([model_ce '/Input Signal']);
All I am chaning is the Rsrc=0, Zload=0 Ohm and adding a line from the beginning of the transmission line:

This is a nice presents a perfect impedance mismatch: The pulse would be reflected entirely at Zload and sent back to the source with opposite polarity. What I expect to see is a pulse of duration 2*Ts = 200ns. Instead, I just see exactly the same pulse as the source pulse:

It seems SimRF does not model reflection properly.
Is this the case or do I get anything wrong?

i met same issue in this.
I even added a 100H inductor. the result was same as.
