Aura (Blasphemy/Life Remnants) behaving Strangely (Intermittenly dropping)

I tried scouring the forums and I can't seem to find anything on this. I'm running Blood Mage (poorly I might add), utilizing Hexblast. I've got two auras I run, Life Remnants and Blasphemy. I've stacked enough Spirit so I have a decent reserve of Spirit, and tried a few different ways in case something was "lowering" my spirit while fighting.

Periodically while fighting Mobs/Packs, both my auras will drop. I have 144 Spirit currently and am reserving 124 (so 20 left over spirit, I was previously using this for another support gem on my Life Remnants, but wondered if something was causing my spirit to drop and remove the auras). I've gone as far as removing the 2nd curse, and having a reserve of 70+.

I can't seem to figure it out, right now my bandaid is to quickly weapon swap, it usually resets and puts my auras back up. I'm not sure if this is a bug or just a mechanic that I am missing.

UPDATE:
Interestingly enough, I reverted back to the older armor I was using, and it seems this bug went away. So it looks like it might bet something related to my newer armor, whether it is a bug or just some interaction I'm not familiar with, maybe someone can help me out. Thank you all so much in advance for any help. I'll continue to update this thread if I find more information:

Previous armor: The Black Doubt. It seems that my Auras do not drop at all.

Current Armor: Couture of Crimson. It seems that my Auras do drop every 30 seconds to minute.
