Spell Effect Persists after Making New Spell

[Alekxos]

I have been using the Creation Kit to make a simple mod in which the Lightning Storm spell no longer disintegrates enemies. However, whether I delete the disintegrate spell effect from Lightning Storm or create an entirely new spell without disintegration and add it via the console to one of my characters in-game, the spell continues to disintegrate anyone it defeats. Any new spells appear in the console and show up as a separate name in the magic sidebar, so I know that my mod is loaded and working. None of my other mods should affect this one either. Is it possible that some other part of the Lightning Storm spell such as the "ShockDamageMassConcAimed" effect is also causing disintegration? Or, is there something else that might be the problem? Any suggestions are greatly appreciated!
