Aura-Stacking Problem

Hello,

Maybe someone of you can shine some light into my problem. Im going mad. I am playing an aura stacking smite scion.like those guys:
https://poe.ninja/challenge/builds?class=Ascendant&item=Ashes-of-the-Stars,Shapers-Touch,March-of-the-Legion,Watchers-Eye,!Voices,!Mageblood,Doryanis-Prototype&skill=Smite&sort=dps

im running more mana reservation efficiency than most of them. (due to my helmet(19%), several 3-passive skills introspection jewels and even specced into 8 additional % at 11 o'clock. but i am not able to run all my auras. i have to disable precission to run wrath. i downlevelt vitallity but this didnt help.i got about as much mana as those chars. what am i missing?here is one char as example(i try to use characters without voices and mageblood that are able to run all those auras according to pob):https://poe.ninja/challenge/builds/char/whitewight/ZanaNoFriendWhite

here is my pob:

i dont now why some skillpoints arent allocated in the introspection clusters when i import them, but they are ingame. every introspection cluster has all points allocated...
