'No Recast' tag not working

[Elizinator]

this is my problem: on a few magic mods i use (Tomebound and Ace Blood Magic) certain spells have stacking effects, which i see as too powerful. now i dont want to just not use the spells, so what i tried to do is edit them. ive tried using the CK and xEdit to apply the "no recast" to the magic effects, but it doesnt have any effect. the spells still stack.

 

what am i doing wrong? how do i make it so that i can only have one instance of a particular spell at a time, like the vanilla armour spells work for example?

also tried using "dispel with keywords", adding keywords hoping to make the spells behave more like those spells, tried Restore tag. nothing works =/
