Sobipro Category Selection

Hey, inside the sobipro integration I have Enable Comments on, and I've chosen Komento Assignment on selected categories, and i have my section and category selected, but entries assigned to those areas are not displaying a comments area. If I turn off on selected categories and just let it show on all, then it displays (but that's not a good thing because we're using sobipro in various capacities on this website and do not want comments everywhere). If I choose categories not selected and I do a reverse select, it doesn't show. That suggests to me there's something wrong with the category select and how it understands sobipro...can you assist?
