How is the Logistic Regression operator determine the category to be left-out from the regression model?  In some tools, the first category is left out, but this does not appear to be the case, at least based on alpha-sorting.  Any insight on the reference category is chosen?  I also attempted to look at the docs for H20, but it's not jumping out to me from this page (though I could be missing something obvious):
