Sub menus not switching language

permalinks settings: postname
static front page : yes, based on template
polylang settings: language set from directory name, hide url for default, remove /language/, detect browser language, synchro – featured image.

the main menu is working correctly, switching between languages. the other menus are not switching though I have a total of 10 menu locations and 10 menus created and assigned appropriately – one for each language for the 5 theme locations defined.

Have following code:
// wp menus
add_theme_support( ‘menus’ );

// registering wp3+ menus
register_nav_menus(
array(
‘main-nav’ => __( ‘Main Menu’, ‘bonestheme’ ), // main nav in header
‘footer-links’ => __( ‘Footer Menu’, ‘bonestheme’ ), // secondary nav in footer
‘location-sub-nav’ => __( ‘Location Sub Menu’, ‘bonestheme’ ), // tertiary nav
‘retail-sub-nav’ => __( ‘Retail Sub Menu’, ‘bonestheme’ ), // tertiary nav
‘sign-sub-nav’ => __( ‘Sign Sub Menu’, ‘bonestheme’ ) // tertiary nav
)
);
