Static front page pagination issue

Using Polylang on a two language / two domain setting with Binder Pro theme breaks pagination on static front page showing offset post loop.

Any page other than the main one gets its number removed, even when input into address bar manually. So instead of site.com/page/2 I get site.com/page and, thus, a 404.
Deactivating Polylang makes the links work.

The theme uses WP_Query to build the loop. Maybe I could change something in that?
Any hints in the right directions greatly appreciated. Thank you!

Here is the theme’s template which creates this loop:

<?php
/**
 * The template used for displaying Blog Modules content
 *
 */
?>

<?php 
$mod_id = get_the_ID();

// Get Blog Module Data
$blog_layout 	= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_layout', true ) );
$blog_columns 	= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_columns', true ) );
$blog_margins 	= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_margins', true ) );
$blog_anim 		= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_anim', true ) );
$blog_perpage 	= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_perpage', true ) );
$show_nav 		= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_show_nav', true ) );
$picker_method 	= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_method', true ) );
$offset 		= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_offset', true ) );
$exclude 		= esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_exclude', true ) );
$blog_perpage 	= $blog_perpage != '' ? $blog_perpage : get_option( 'posts_per_page' );

// Define Animations
$anim = $blog_layout == 'masonry' ? 'anim-grid' : '';

// Now, let's query for blog posts
global $paged;
$page_var = is_front_page() ? 'page' : 'paged';
$paged = (get_query_var($page_var)) ? get_query_var($page_var) : 1;
$offset = $paged == 1 ? $offset : ( $offset + ( $paged - 1 ) * $blog_perpage );
$args = array(
	'post_type' =>  'post',
	'posts_per_page' => $blog_perpage,
	'paged' => $paged,
	'offset' => $offset,
	'post__not_in' => explode( ',', $exclude )
 );

// Modify Query depending on the selected Show Method
if ( $picker_method == 'tax' ) {
	// Bring Selected Categories
	$sel_terms = esc_attr( get_post_meta( $mod_id, 'quadro_mod_blog_terms', true ) );
	if ( $sel_terms != '' ) {
		// Add tax query to query arguments
		$args['cat'] = $sel_terms;
	}
}
elseif ( $picker_method == 'format' ) {
	// Bring selected post formats
	$args = quadro_add_selected_formats( $mod_id, 'quadro_mod_blog_formats', $args );
}
elseif ( $picker_method == 'custom' ) {
	// Bring picked posts if there are some
	$args = quadro_add_selected_posts( $mod_id, 'quadro_mod_pick_blog', $args );
}

$wp_query = new WP_Query( $args );
?>
