BuddyPress.org

If I leave it blank or deselect checkboxes (or any applicable action that means leaving it blank/unused) the information does not disappear from the user profile. The previously active checkboxes still show, the deleted information in the text field still shows, etc.

If you go back to the “edit” screen the checkboxes will still be deselected and the text field will still be empty, and hitting “submit” will give you a success message, but the info will still show on the viewable profile.
