Twitter embed not showing full card

I’m having a very strange issue. I paste the Twitter link in to the editor in text, and if I switch to visual it shows the full Twitter card. On the front end though, it’s pulling info from the Tweet, but not the full card. I’m not seeing any JS errors or anything. Any help would be hugely appreciated
