When I moved another profile, the tool somehow made my own profile the brother of this one https://www.geni.com/people/Sigrid-S%C3%B8rhuus/6000000105390252869#/tab/revision
The relationship to a set of unknown parents was added to both, but when I edited the relationships of either profile (mine or Sigrid Halvorsdatter), there was no option to delete this relationship, created in error.
