Can't Delete Some Sections

I’m working on a page where the bottom half of the page no longer provides any editing options and the text styling is gone. I can’t even delete the sections let alone edit them. The upper half of the page works just fine and I can edit it. I have already uninstalled all plugins. I have worked on both Chrome and Firefox and the issue is the same on both browsers. Any thoughts on why this is happening? Happy to provide login info.
