Why does the FSJ4 show that result? Note that when terminating that run into 50 ohms, the step response reflection coefficient is zero across the run.

Can you make sweeps with far end open and short, then export to AC6LA's ZPlots Excel spreadsheet and have it compute the TL parameters? This might provide some clues.

Note that ZPlots only runs in Excel, not alternative spreadsheets.
