Hello again Dascanto,
Kindly, let me clarify some points for you while replying to your questions,
1- The demos aren’t different. They are the same but you just need to have the same posts & categories as we have in order to see the same result.
2- Make sure your time won’t be wasted. Choosing the type of posts you want to show in the page builder is essential, otherwise you will show the posts we chosen (in case you have the original content)
3- If you want to see the exact same demo, please proceed to the 1-click demo installation explained here:
This will create all the pages, blog posts and portfolio posts as we have in the online demo. You shouldn’t do this if you already have your content and pages on the website.
4- The page builder has nothing to do with the header and menu, this is built using another builder which I linked it to you above. This is also pretty easy and I believe it won’t take much time.
If you needed any further assistance, please let me know immediately.
