Add <Any> in all selects in Views Hierarchical Select Filter

The schema is nodes with a Node Reference to a table Area, this ones has a NR to Cities and this one to States. I have a View with a Hierarchical Select Node Reference filter to filter the nodes by location. (Properties -> State -> City -> Area). In properties, for the the node reference I'm using a Hierarchical Select with 3 values, and saving the lineage.

It works if I choose the state (provincia), the city (municipio) and the area (zona), or if I select in state, but when I'm only selecting State, or State and City, the result is empty. There should be a option in every select. I have checked Optional in the filter.

Can anyone help please?

This is the view exported:

$view = new view;
$view->name = 'filtro_inmuebles';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
