How to delete an episode from a series?

Hello, The problem concerns this page (https://www.imdb.com/fr/title/tt1782675/), an episode of the french series"En votre âme et conscience". The problem is that 'les joyeuses commères de Windsor' is NOT an episode of the series "En votre âme et conscience" (a french series about famous trials), but an independent movie (adaptation of the play by Shakespeare 'The Merry Wives of Windsor', no connection to the theme of the trials). The title is already on Imdb (https://www.imdb.com/fr/title/tt38789169/). I couldn't find how to request the deletion of this episode. I tried it that way (251028-210719-853000), but il was declined. Could you delete this episode which is an error? Thank you.
