Aura vs Buff display

[thumbsmasher]

I am a nUI+ noob, trying to get my display set up. Per the nUI-elements.jpg on the nUI homepage, the icons located between the health bars are 'auras', and the frame on the left, above the chat panel contains 'buffs', but when I set my 'maxauras' to <0>, both the auras AND the buffs disappear. I would like to lose the auras, and keep the buffs. What am I doing wrong?

It would also be nice if the cooldown bar went away....

Thanks in advance...
