Sorry I do not understand what you mean. In the user profile should appear the biographical information that is added from the admin panel. In the following link you can see my profile that does not appear description
I don’t think I can advise you. BuddyPress does not some built in with a personal description. You can add one, in Dashboard>>Users>>Profile Fields, and it would be displayed during signup and in the users Profile>>View page. However, that’s not the default landing page for a profile, so it looks like your theme is overloading the users profile, and I think your theme developers would be best placed to ask.
