Find bug in [wpsl_address] shortcode

Not workin any false parameters.
Resolving by adding this code:

foreach ( $atts as $key => $val ) {
                if ( is_string($val) && $val == 'false' ) {
                    $atts[$key] = false;
                }
            }

After call of shortcode_atts in class-frontend.php of function show_store_address( $atts )
