Buddypress CSS overrides Child CSS

Hi there,

I'm trying to change the background color of some elements in the Social theme and it seems that Buddypress CSS is taking priority in some cases. I thought that the Child CSS was the highest priority. Specifically, I'm seeing that:

div.item-list-tabs { background: #EAEAEA; } from bp-default.css is ranking higher than

div.item-list-tabs { background: #BCD3E1; } from child-style.css

Does this mean that I should be altering this color somewhere else?
