Header cannot be edited without coding

You have mentioned on the ad of your theme that no coding required, my question is how can i edit the header? there is no any plugin to edit the headers and even on the page body many titles built as headers and cannot be edited with the front end or backend of WPBakery builder!

I want to make so many changes on the header and it is very difficult to keep opening a ticket every time i want to edit something on headers.
