The Hit List Season 6 contains three duplicate episodes: https://www.tvmaze.com/seasons/146049/the-hit-list-season-6/episodes . They should be removed, and perhaps the episodes should be renumbered (to match both BBC and IMDb). Perhaps the episodes from The Hit List Celebrity Specials should be in there as well: https://www.tvmaze.com/seasons/153573/the-hit-list-celebrity-specials-season-4/episodes . The BBC Episode Guide places them in the regular list for this season: https://www.bbc.co.uk/programmes/m0005j3y/episodes/guide
