BuddyPress.org

Have you tried switching momentarily to a WP theme like 2016?
If you do and the problems are resolved, then you know the issue is in your theme and you should speak to the theme creators.

BuddyPress does not add a random description or social icons.
You may also want to try deactivating plugins one at a time until you identify the source of the issue.
Then you can contact the developers for that plugin.
