Duels passive treasure batch system broken

I would like to repport a bug in the duels gamemode i hearthstone. I just started a Turalyon (Paladin) duels deck and after my first battle i get to chose a minor passive treasure. But my problem is of the 3 treasures im offred, two are discover based treasures (Open the doorways and Staking a claim) in my decklist i don’t have a single card with the keyword “Discover” and therefore these are useless and shoulden’t be in the pool of treasures avaliable to me. Just like how deathrattle, elemental (like freeze or spelltype) or tribal treasures get sorte out of the pool if your deck contain none of these.
