Still wondering about the Sealed Mode

Hi,
I'm still wondering about the Sealed Mode, is that Mode supposed to work correctly right now? There just is a tone of errors with the AI and how it "builds" its decks, like sometimes adding no lands to its decks or only playing Blue/White and so on.
Is that all known or even some error on my end?
