Can custom fields be deleted if data has been captured in said fields?

Custom Fields can be deleted regardless of whether or not information has already been processed for that particular field.

If information has been processed in the field that is being deleted,  a pop-up message will appear to confirm the deletion (after the element is deleted, before the screen is updated).
