Level 2 Enlighten Fails to Reduce Mana Reservation

Simply removing Enlighten from my Shavronne's Wrappings fails to change my health pool. My health pool is in fact regenerating because I am using a Vitality aura without Zealot's Oath. There are two auras, Wrath and Anger, linked to the level 2 Enlighten & a Generosity gem.

There are two other level 3 Enlighten gems in my gloves and helmet supporting only aura gems. When switching the Enlighten gems around, I don't see any other mana reservation issues.

Perhaps Enlighten (or, specifically, a level 2 Enlighten) will fail to reduce mana reservation properly when linked to auras supported by Generosity.

Is there any other information you need?

Two screenshots of "toggling" (right clicking to remove the Enlighten) from my Shav's:

Unsocketed:

As Vipermagi would say, it's not a bug...just math. The .96 multiplier isn't enough to get your reservations a percentage lower because of rounding.

Without knowing how much reduced reservation you have and level of blood magic gem, I can't be more specific with numbers.

Thank you. That is rather annoying. After some further investigation I've found your answer correctly describes my issue.

P.S. Not using a Blood magic gem. It's blood magic from the passive tree.
P.S.S. Enlighten has a text error in my screenshots at "don't." Will make a new post.
