Trial of the Sekhemas: Bugged Affliction "Winter Drought"

I just ran into a bug with the "Winter Drought" affliction in Trial of the Sekhemas. Winter Drought states that you will "Lose all Sacred Water on floor completion." but instead of wiping your Sacred Water upon moving onto the next floor, its wiped immediately upon defeating the boss of your CURRENT floor, preventing you from being able spend any of it at the shop.

Not sure if this bug is exclusive to the 4 floor trials only? As "Winter Drought" did not function this way during my 3 floor trial attempts and instead gave me a chance to spend my Sacred Water before moving onto the next floor.
