Thanks for writing in! As mentioned on our demo content generation area, standard demos only includes home page along with image placeholders and example posts. If you want to try a full demo including inner pages with content and images, please try generating one of our expanded demos.
Also make sure to install and activate Slider Revolution plugin under X -> Validation -> Extensions area, before generating your demo content. So that it will import your sliders as well, while your demo content is generating.
You can also check all the demo examples from the following link (https://theme.co/x/demos/).
Hope that helps.
