When I am selecting a section it is also adding to other pages. I want to take section for the specific page. Another serious thing is when I am deleting the section from other pages it also deletes from main pages. I do not understand what is going on and is this a bug? Is there any solution to you?

There is a new problem now. Whenever I take a element it is in every page and when i delete any element it also deleted from every other pages.

What is wrong with your system?
