The description of the character

Hello, I have a question. In the episode the description of the character is as follows: O'Shaughnessy, Nicholas Author, 'Selling Hitler: Propaganda and the Nazi Brand', Quondam Fellow, Hughes Hall, Cambridge University I followed the example of other entries on imdb: 1) Self - Author, 'Selling Hitler: Propaganda and the Nazi Brand' (O'Shaughnessy in Hitler's Propaganda Machine, https://www.imdb.com/title/tt9394860/fullcredits/?ref_=tt_cst_sm) and 2) Self - Quondam Fellow, Hughes Hall, Cambridge University (O'Shaughnessy in Augusto Pinochet: The Coup, the Torture & the West, https://www.imdb.com/title/tt29611917/fullcredits/?ref_=tt_cst_sm) and I sent the description Name: O'Shaughnessy, Nicholas Character: Self - Author, 'Selling Hitler: Propaganda and the Nazi Brand'/Self - Quondam Fellow, Hughes Hall, Cambridge University (#250716-085004-078000) Why in other cases such a description was accepted and mine was not? Thank you for your answer. Rafał
