Problem:
Get the ID of the WooCommerce shop page with get_option('woocommerce_shop_page_id') on a translated page

Solution:

Our developers are checking the issue.

In the meantime I am suggesting you 2 workarounds.

1) Use

1
wc_get_page_id( 'shop' )
2) Go to woocommerce-multilingual/inc/class-wcml-store-pages.php around line 208

$addFilter = function( $slug ) use ( $convertPageId ) {
    add_filter( 'woocommerce_get_' . $slug . '_page_id', $convertPageId );
        };

and change into this :

$addFilter = function( $slug ) use ( $convertPageId ) {
        add_filter( 'woocommerce_get_' . $slug . '_page_id', $convertPageId );
        add_filter( 'option_woocommerce_' . $slug . '_page_id', $convertPageId );
        };
