The plugin doesn’t filter the posts by languages.

I try to embed the popular post list with the following PHP code, but posts in different languages are still mixed in the list as shown in the attached URL.

I’m using Polylang Pro as my multi-language plugin and it’s updated to version (3.1.5) and the latest version of WordPress Popular Posts (6.0.4)

$language = array(
	'ja'     => 1502, //these are the term_id I found in the database
	'zh_TW'  => 1504,
	'en'     => 7623,
);
wpp_get_mostpopular( 
	array(
		'limit'           => 5,
		'range'           => 'last7days',
		'stats_views'     => 0,
		'taxonomy'        => 'language',
		'term_id'         => strval( $language[ get_locale() ] ),
	)
);
