to replicate:

-create new board in pcbnew, set some custom track withs in the global design rules editor.
Now you can select these new withs to lay some tracks on the board.

- save the board

- close pcbnew

- start pcbnew, opening the saved file
The new track withs don't show up in the track width chooser box, but they are saved in the global design rules table.

I have to go to the design rules editor and press OK to 'activate' them so I can use them again.

Via settings have the same problem.
