exporting S1P file with sw Nano VNA-Saver yields wrong data

I closed my issue by making a mistake.
Here it is again.
I compared 3 S1P files.
All generated with the same way of calibrating, and the same DUT.
one generated with a R&S ZNC-3, one with nano-VNA and -saver, and one with nanovna and sharp SW.

Calculating from the S1P files back to the marker value readings the R&S ZNC3 and the combination nanoVNA with Sharp succeeds, the combination nanovna with Saver fails.

conclusion: The nanovna-Saver software exports erroneous S1P files.
I enclose all 3 S1P files for investigation.
sharp.s1p.zip
znc3.s1p.zip
nanovna_result.s1p.zip

For a nice application, measuring the complex permeability of toroids by measuring S11
it is important to have good data, so my request is a bug fix.
Used SW version info:
version_info

NanoVNA as hardware not export s1p files
Export NanoVNASaver software, it should made correct format of file
You can try ask on NanoVNASaver repo
https://github.com/mihtjel/nanovna-saver
But as i know dewelopwer not ask ¬3 mounth
Or you can ask on NanoVNA forum
