Why can't I see my walls, door, and roof in Sims 4?

I bought my house mobilized and only changed a few pieces of furniture and made rooms bigger. However, I can no longer see my walls, my roof and my door (I play on the ps4)

Loose contact in the eyes

So I play Sims on the PC but you have probably changed the view so clicked on this room that the walls go away I unfortunately don't know what it looks like on the PS4 but for me it's this symbol
