Proposed Fix for WPML

To fix the issue with WMPL, simply add

'suppress_filters' => 0,

on line 117 of class-wp-notification-bars-shared.php,
the code should look like this:

$args = array(
				'post_type' => 'mts_notification_bar',
				'posts_per_page' => -1,
				'post_status' => 'publish',
				'suppress_filters' => 0,
			);

			$all_bars = get_posts( $args );
