Per TVmaze policy: Rewriting history after an episode has premiered is never accepted. For example, if a show's official website indicates that a certain episode belongs to season 1, but changes it to season 2 a year afterwards, it should remain listed as season 1.Originally those episodes were presented as specials, and the first non-special episode was "The Watsons Family" https://web.archive.org/web/20171220050525/http://www.channel4.com/programmes/the-crystal-maze/episode-guide
Only a year later C4 changed their episode guide, listing the first pack of special episodes as series 1.
I can't see on that archive link where it says that the Watson Family is Series one, just says a new series in the description.
