BuddyPress.org

I just installed Buddpypress and it looks fine on the home page (groups list) but when a group is selected, and you go to that page, the sidebar gets forced down and the groups messages show across the entire width. I’m working with a Child theme and not sure how to change the CSS because the widget/sidebar placement is fine on the homepage. Here’s a pic of how it looks when you go to a group: https://freevps.us/img/images/buddypjxj.png
Thanks for any help you can provide.
