Scrying Cristal boon not applied after first room finished

Hey! This might be the intended behaviour, but I had the following experience with the Scrying Crystal boon in the Sanctum:

Preexisting curse that might be relevant: Golden Smoke "Rewards are unknonw on the Sanctum Map"
Buy Scrying Crystal "You can see an additional room ahead on the Sanctummap" (trader on 7th room of floor)
Defeat boss and get to the next floor. Can see one room ahead (that is 2 rooms), but cannot see rewards as intended - only if it's curse or non-curse room.
Visit the sanctum for the next room, I am no longer able to see two rooms ahead only one, still without the rewards.

If this is intended then perhaps a wording change would be warrant as I though the boon would last the entire sanctum not just one room.

Thank you, have a nice day

Oh... I was worng... It's just that there hasn't been any cursed room for the next couple of rooms and thus there was nothing to show, but as I reached a part of the floor that has such rooms I can see them 2 floors ahead.

Sorry for the false alarm.
