I may be wrong but there's a little difference between ??? And Unclassified.

??? Somehow act as a "True" class, Where Gore Magala, Estrellian and some MHST Monsters are included in this class for a reason.

"Unclassified" is not an offical class at all, name self explanatory. Laviente and Duremudira are unclassified simply because doesn't have any class.

As for now is not a bad idea to include Behemoth as "Unclassified" then of course will be better to change it in case if its class will be revealed.
