Staff: Keyword help needed

Would you please delete the keyword “madrid” from:

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?
