Hi Glen,
IMHO it is only a problem of resetting charts.
As you have a frequency range problem:
1) Point the mouse cursor on the chart that show the wrong behaviuor.
2) right click to show the chart management menu.
3) On such menu left click Reset because the VNA Saver could have some "memory" of previous measurement
4) Then always on this menu choose Frequency axis and left click on Automatic
5) Alternatively you can choose Frequncy axis then customize the minimum and maximum frequency.
Sometime the problem is on Data Axis ( vertical ) and the chart management menu can help too.
