Blight Atlas passives that reduce cost of Towers/Upgrades Bug

I have both [Blight Tower Cost] nodes on the bottom left of the Atlas Tree allocated, and after going through different maps (Kirac, with enchantment that grants Blight, regular maps, Blighted maps, and anointed Blighted maps) this passive only seems to work in half the time.

In a Kirac map where the mission is to complete a Blight encounter (including a blighted map from Kirac), it doesn't reduce the cost.

In an anointed blighted map, it doesn't reduced the cost.

In a standard map with an enchantment, it does reduce the cost.

In a standard map that you happen to find one in, it does reduce the cost.

I grabbed a screenshot after submitting a /bug report in-game, since it told me to. This was just after completing a T16 Anointed Blighted Map and realizing that I was only getting the reduction from two Amber oils, which finally prompted me to submit this.

I see, my misunderstanding on things then. Didn't realize!
