Avada (disable functionality)

I don’t know if this is the right place to post this but I couldn’t find anywhere else. I have installed the Theme Avada and its child theme. The child theme is activated. When I go into the page editor a lot of the functionality is disabled. So far I have found that (‘Add Media, Screen options, add shortcodes, edit image and visual and text view’) do not work.
I have tried deactivating the plugins and activating them one by one again. I have deleted wordpress entirely and re-installed it and started.
It’s driving me mad to have paid for a theme that isn’t working. Has anyone come across these issues before.
