[LD] Picture in legacy family portrait disappears

I am playing on a laptop (Windows 11). In the meantime, I checked other households, and the portraits were not affected. My sims were living in a duplex (residential rental), and the other part of the duplex was rented to other sims. I moved them in a city apartment, and the portrait was fine. I did not check other households that live in a residential rental building because they were my only sims that owned this kind of property. But I am going to check it tonight with other sims and see whether the problem is still there or not. Thank you for your answer!
