how to delete buddypress theme pack from my theme?

I'm trying to customize some of the layout of buddypress pages. I'd like to mod the code bp default theme files, but I have installed and activated the "BuddyPress theme pack" plugin which has installed several required folders in my child theme on my server. They seem to overwrite the core bp default theme. Problem is, they can't be edited, OR EVEN DELETED. (WTF - Hijacking my server???)

How can I delete the bp-theme-pack folders and files from my child theme?
