Niightbreed is the official film title it’s an American film production from Morgan Creek.
Nightbreed aka Cabal is the same film
The first compromise Barker made when making the film was to change the title of the film from Cabal to Nightbreed because Morgan Creek insisted on a more commercial title.
Nightbreed was released in France as Cabal, the title of Barker's novella on which the film is based.
It’s not unusual for film releases in different countries to use alternative titles and home media releases use that alternative film title.
Italy and Germany also done Blu-ray releases using Cabal as film title on artwork.
The problem I see with some countries using Cabal as the only film title on home media releases some people might confuse a release to be The Cabal Cut when those releases are only the Theatrical or Director's cut versions of Nightbreed.
The only Official Blu-ray release of The Cabal Cut was a very limited Clive Barker Store Exclusive in USA.
