We checked the updated theme and it is fine here. Would you please check once on Appearance > Customize > Featured Section > Featured Slider Options and check there is parent page selected or not. If you select the parent page, its child pages will appear as slider. In case of free theme, only text will slide. The title and content of child pages will slide there. You will get more options in case of slider and lots of other widget to make your site more awesome.
