The Beaker family isn’t showing up in gallery

I want to know if this is happening for other people or if it’s just me not having the required packs for them. You see the Beaker family does not show up in my gallery I’ve searched and it’s updated idk what I’m doing wrong. To add to this I also haven’t seen the Specter or that one half alien half sim family that is also from the sims 2 how do I fix this? Can I even fix this?
