death knight issue - timers over action bars

[talk2mark]

New to nui so this may be simple to answer:
Upon entering combat, a bar appears on top of my top-most action bar in the center, showing countdowns for all cooldown-related attacks. It is blocking my icons on the action bar that allow me to fight. How do i remove?

I have disabled all add-ons except nui, and this problem exists so it must be some toggle command i am not familiar with. Help is appreciated.

Edit: Solution is type /nui hud cooldown to eliminate this across all toons.
