@vejai2 Hello! I'm sorry you've been having so much trouble. Have you checked all their ages? For married couples, the sims have to be young adult or older. Meaning teens and adults can't be married to each other. For family relationships, parents must be older than their children. I'll use the young adult you highlighted in your image as an example. If you want to make him a parent of a young adult, then you'd have to change his age to adult or elder. This is a limit of CAS. When playing the game and you have aging turned off, it is possible for a teen to age up to young adult while their parent remains young adult too. You won't be able to do this in CAS though.
