This question may have already been asked, if so I was unable to find it.
When setting the design rules for a PCB, how does one set the setting for the default net class? Whenever I set them via the Design Rules Editor they are changed for that session only, the Track Width, Diff Pair Width and Diff Pair Gap are all changed ever time I restart PCBNew. I can't find where these incorrect values are coming from.
Track Width keeps defaulting back to 0.25mm, Diff Pair Width defaults back to 0.2mm and Diff Pair Gap defaults back to 0.25mm
