It is perfectly clear now.
I firstly had made the calibration on the NanoVna and saved that in slot 0.
Then connected the NanoVna (by pressing the "Connecting to device").
Selected the wanted segments (let say 10) and frequency range.
Opened the calibration menu.
Pressed Reset in this menu (it does not reset the calibration in the device).
The cal components show Uncalibrated".
After the calibration the Cal Thru is perfect 0 db.
And that is what I expected.
Coming back on your remark " This was made clear by the the original author, Rune, in a post when he first released NanoVNA Saver.",? I had read the warning in BOLD? in Rune his opening window when you start with the calibration in NanoVna Saver.
So basically I was warned.....
Issue solved.

From what I understand you are resetting the cal in the NanoVNA before connecting to NanoVNA Saver. When calibrating with the Calibration Assistant in the PC program NanoVNA Saver you should already have the NanoVNA calibrated over a range larger than the range you want. This was made clear by the the original author, Rune, in a post when he first released NanoVNA Saver. You can search the group for his post.
