visual composer jammed one page

I’ve been using visual composer with very few issues (beside not knowing how to use it) for a few weeks… I’m nearing completion of my site and now, on one page only, it’s jammed up. All the other pages will open for editing except the one I want…

After googling some other fixes, I deleted the plugin, cleared the cache and reinstalled the plugin, but it’s still happening.

How do I fix this?
