Help with boss cast bars ui [addon] [help]

I don't know if it's weak auras or default blizzard UI but when it's a boss fight the boss cast bars and channels are covering my weak auras making it impossible to see my buffs. And as an arcane mage I really need to see my procs and buffs. I've tried edit mode but it's not showing up. I'd like to get rid of them as plater nameplates already shows me the cast bar under the health bar.
