Even when the ADD buttons are displayed, I think that the best way to create profiles from GEDCOMpare is to work from the "Compare" report for an individual already matched. When you do this, it's easier to be sure which family group you are editing, and it reduces the risk of possibly losing some of the connections between family members.
However you use GEDCOMpare to create profiles, you should plan to review the record and edit it, because there is likely to be some clutter, and the import might not look as good as you hoped it would.
