How to set a page with Multiple wp_Query

Hi everybody,
i create a page with a custom template-page that show posts with several wp_query like this:
$the_query = new WP_Query( 'category_name=exhibitions&tag=2016&posts_per_page=-1&orderby=date&order=ASC' );

in principal language it works well but when i change language with polylang No contents are shows.

i also customized another template that is setted up to the translated page with the query made by category_name translated.

what’s the error?
what is the correct way to configura a page with multiple queries?

tnx
