I have the same issue as @Maysbat.
If I create a new save, the NPCs have the right preexisting relationships, but when I play my existing save, the NPCs have no relationships on the relationship panel.
Ex: I checked the Pancakes and the Vatores. Both families had the correct relationships assigned in CAS (brother/sister, husband/wife) but their relationship panels were all empty.
So I just checked an old save of mine that I haven't touched in a while and the sentiment is there
So all seems normal to me. Maybe it goes away really fast ?
