can`t delete last tracker in Trackers

[simur612]

Choose one torrent in list.
In "Trackers" click right mouse button, choose "Edit torrent...". Delete last tracker in "trackers", press "Ok" and nothing happened. Tracker not deleted. If I delete not last tracker in list everything fine.
Why I can`t delete last tracker?
