How to get BuddyPress Members to show up in Multisite

I have imported roughly 50 members into one of the blogs in my WP Multisite install. I'm using BuddyPress on the blog. I am trying to get all members to show in the member directory. I am aware about the latest_activity function, but that doesn't seem to work. I've tried to change the default member directory listing to show by Alphabetical order, however this shows ever user in the database and not just the members of the blog. Ultimately I'd like to show members in alphabetical order, but I need to find a way to not show every user in the WP Multisite database. Please advise on how I could accomplish this.
