Suggested correction: I don't see any crew. I'm watching it on Netflix. Perhaps they fixed or perhaps they edited it out after realizing the mistake. But they aren't there anymore.
Even if Netflix corrected the mistake doesn't mean the mistake is now invalid if the mistake existed in the original BBC One airing. Netflix is known to change or edit programs they stream (such as replacing soundtrack songs).
