Is “import categories - show imports in familes” turned on? that node takes the geometry to .sat and then in turn imports that .sat to a family. if you have imports in family turned off - then you cant see the resultant family.
also in the family browser you can check to see if it created the family - if it did and you edit the family is the geometry there? if so - then it’s likely just your view’s VG settings that are keeping it hidden
