Where does Beer Smith get its user entered gravity and volume fields on the fermentation tab when a new recipe is created? I have found that whenever I make a new recipe these fields that I should be entering data into myself are populated with what looks like arbitrary numbers. I would like all of those fields to be set to 0.000 when I make a new recipe so that my actual efficiency and ABV numbers show 0.0% until I actually have brewed the beer.
