change to miniseries

Greetings, I noticed that the title for "Bad Host: Hunting the Couchsurfing Predator" is a single documentary but through my research it's actually a miniseries with three episodes, could someone within the imdb staff change the genre for this title (I've included below several sources to further prove its a miniseries)? https://www.themoviedb.org/tv/241370-bad-host-hunting-the-couchsurfing-predator/season/1 https://trakt.tv/shows/bad-host-hunting-the-couchsurfing-predator/seasons/all thanks for your help
