Sims builds wont load properly

I've been playing the Sims for just over a month and a half and know the controls well. I play on Xbox so I can't have mods, but for some reason my house on my favourite save won't delete properly, when it does and I replace it with the one I want that one doesn't load properly. I do use packs but the only one the house I picked actually uses is cottage living, and none of the comments on the gallery say it has mods or anything like that. I don't understand why the build has nothing outside, any windows or any indoor decorations, when its not like that on the photos. I can't tell whether my game is breaking or whether the person just uploaded it empty or smth. I made sure i chose furnished, so it makes no sense why it is empty.
