buddypress group chat styiling not working

Hello guys!
So i'm trying to style the group chat in buddypress, but anything i change in the backend simply doesn't show up in the front.
I tried doing my changes in the settings page, settings dashboard, settings widgets, all of them, but i can't get them to work. I wanted to add names alongside the avatars, and style the chat a bit.

What am i doing wrong?

I've also granted access for you in the dashboard.
