I believe that for Secret Chamber as the bane for Young Witch, it should ask you separately whether you want to reveal it as a response to an attack (to flip around the top cards of your deck) and whether to reveal it as a Bane for Young Witch? Or something?
Secret chamber is weird. In general, reactions CAN be revealed multiple times, but in virtually all cases there's no benefit to doing so; in the case of Young Witch/Secret Chamber, you DO have to reveal it twice, for different reasons. So you might have to say 'yes, no, yes' to the isotropic prompts if you want to reveal it for its ability, then not reveal it again for its ability, and then reveal it for the bane.
I don't know why it asked you four times. Maybe Doug put in a thing where it only lets you reveal four times, because even though you COULD reveal it more according to the rules, that's just stupid and you should cut people off so they don't stall.
