I am trying to change the advance factor setting for my substrate (from advanced settings) and the new value does not save. What i noticed was I can enter a number in the box by clicking on the -ve and +ve buttons for advance factor and either I go back (since there is no save button on this screen) or if I scroll the down to the extent that the advance factor box goes out of the view and comeback to it, its value changes to the default 0. So essentially there is no way of saving the new value. see screenshots.
