Staff: Keyword help needed

Would you please delete the keyword “madrid” from: “Por H o por B” (2020-20200 Would you please delete the keyword “istanbul” from: “Kulup" (2021-2922) Would you please delete the keyword "Bucharest" from: Water (2002) Would you please delete the keyword “life-story” form: “Biggie: I Got a Story to Tell (2021) Would you please delete the keyword “crime-documentary” from: 800 metros (2022-2022) Would you please delete the keyword “biographical-documentary” from: Biography (1987- ) These have all been submitted one or two times, but seem to be victims of that “lingering, hangover” situation where IMDb “holds on” to a keyword when that same keyword has been deleted for OTHER titles. Sure would like to know why this happens.  Is it a technical problem, or are such titles, for some reason, blocked from deletions?
