Vassal civil war

Hi, and thanks in advance. But I am trying to play the Civil War game with the Far West Variant option in it. I load it set it up from the year/turn I want and when I close it and try to reopen it nothing is saved.
I after starting it I do the log file and when done setting it up I end the log file, but not sure I need to save it as well or…
But regardless it doesn’t seem to save any changes I make to it. Can anyone help thanks?
