Many expanded trainers and energies missing

Most of expanded format only trainers and energy cards aren't available in the expanded format: you can craft them, but the game doesn't allow you to play it. Right now i found: Computer search, N, Pokemon Ranger, trainer's mail, VS seeker, Proffessor's letter, float stone, sky field, Silent lab and double dragon energy. All of these cards aren' banned in normal expanded, so i don't know why i can't use them on live

Also, if you import computer search from a deck list the game automatically puts it with the pokemon cards instead of the trainer cards, i dunno why
