Help with Supreme Magicka

[Sigral]

So, I try and use Supreme Magicka, and it removes my default spells except Greater Powers. Like, I can start a character and he'll have the usual Flare and Restore Health spells you get from the start. I activate Supreme Magicka, and the spells are removed from my spellbook. Can anyone shed some light on why this is happening? Other than More Magicka, I don't use any mods that affect magic or combat.

 

I try Supreme Magicka with only its main file, and it still occurs. I activate the Shivering Isles file, same problem.

 

I use Nexus Mod Manager to download, and yes I have the latest version of OBSE and Oblivion (GotY).

 

Plz halp.
