Why appears a duplicate section cell while-in-search-mode in UITableViewController?

Why appears a duplicate section with one empty cell (or even maybe table) behind my cells that ar开发者_运维知识库e the results of the search? That dummy cell appears when I'm dragging my real on-top cells to the bottom.

UPDATE: However, I do not see a duplicate tableView in my xib file:

Looks like duplicate and never happened to me before. Haven't you accidentally allocated another table view object? What about viewDidLoad or loadView?
