Probleam after updating perch runway cms and blog app

I am using following code to get news form blog APP.

perch_blog_custom(array(

'blog' => 'news',

'template' => 'post_in_list.html',

'count' => 10,

'page-links'=>true,

'filter'=>array(

array(

'filter' => 'language_list',

'match' => 'eq',

'value' => 'en',

),

array(

'filter'=>'site_list',

'match'=>'eq',

'value'=>'my_site',

),

),

'sort' => 'postDateTime',

'sort-order' => 'DESC',

));

Before updating the perch in 2.8 version this code was working but in new version 3.0 news is not getting filtered based on the language_list and site_list.

language_list and site_list both are custom field types.

Could you please help us on this filter issue.

Thanks
