No theme content for Wen Business Pro

Hi I installed this theme but I don't see any content, just empty pages with some texts. How do I load the full theme like it shows on the demo page? https://catchthemes.com/demo/wen-business/ Then I can update my picture and change the text... I hope I didn't bought only extra widgets and menu bars which I need to use to build the site more of less from scratch Thank you for your support
