Eldritch Altar gives wrong eldritch currency reward (#4,126,261,859)

Ran a T15 map with Searing Exarch Influence. Altar let me select a reward to guarantee the boss would drop Eldritch Ember currency (emphasis mine) and then killed the boss; instead, got a mix of Ember currency and non-Ember Eldritch currency.

I'm not sure whether this is a typo or an outright bug; Since the text & drop contradict each other, one of them is incorrect, since the text says "Eldritch Ember Currency" while the drop table is "Any Eldritch Currency, Ember or not." (again, emphasis mine)

Bug Report #: 4,126,261,859. Not sure if the report is useful or not. May be superflous if bug proves to be consistently reproducible.

Reproduction: Possibly reproducible, RNG willing: run Searing Exarch-influenced maps, and find the exact same reward type ("Drops # additional Eldritch Ember Currency Items") and repeat to find that you get non-Ember currency.

Screenshot: Attacked is a screencap showing the altar in question, alongside the two currency items dropped by the map boss dropped onto the ground for comparison.
