There is a major UX discrepancy in describing something as "Mutuals" without distinguishing Groups and Friends into two distinct categories. Without the distinction, people immediately assume the term "Mutuals" refers to individuals, as opposed to BOTH individuals and groups. These should be separated to avoid confusion, or the 'Mutuals" are should be renamed to something better suited. Unfortunately, I don't know anything short and sweet, but it may be better to just name it something closer to "Relations" instead.
