@tatyana-gold I think this is similar ot tied to the same issue as discussed here: Families lose avatar icons
At the moment the pictures are only displayed for the original in-game families. And it seems these are also static. Meaning the updates in age or family members do not show. E.g. if you would add one of your Zois to a premade in-game family the Zoi would also not appear in the picture.
As for Zoi households you created yourself there are no pictures at all - likely the first household in your screenshot. This should change soon when we will be able to make family pictures for our own family as well - see in the other thread. This has been annouced by Kjun in one of the latest news posts.
