Hi underground studios, I wanna share you something related to your problem.
Have you tried following the Documentation? can be found here only under OUR SUPPORT>Documentation.
This is STEP 6 saying:
“6. Demo Data Installation
The next step gives the opportunity to install automatically demo content.
Firstly go to Theme Options > Import/Export, press Install base demo content button to install products, categories, posts, projects, some pages. Only after that you’ll be able to install other theme versions correctly!”
Hope that helps! If not they will help you.
ChEers!
