WCML

Problem:
You are trying to set 'Set prices in other currencies manually' as the default choice on the product page for variations, but the WooCommerce Multilingual plugin defaults to 'Calculate prices in other currencies automatically', causing manually set prices to be ignored.
Solution:
Since there is no central feature in the WooCommerce Multilingual plugin to switch to the manual price option for variations, you need to use custom coding. Add the following code to the functions.php file of your theme to set 'Set prices in other currencies manually' as the default for new product variations:

function set_default_manual_currency_pricing($post_id) {<br />    if (get_post_type($post_id) === 'product_variation') {<br />        update_post_meta($post_id, '_wcml_custom_prices_status', '1');<br />    }<br />}<br />add_action('save_post', 'set_default_manual_currency_pricing', 20, 1);

To apply this change to existing product variations, add this code, run it once, and then remove or comment it out:

function update_existing_variations_to_manual() {<br />    $args = array(<br />        'post_type'   => 'product_variation',<br />        'post_status' => 'publish',<br />        'numberposts' => -1,<br />    );<br /><br />    $variations = get_posts($args);<br /><br />    foreach ($variations as $variation) {<br />        update_post_meta($variation->ID, '_wcml_custom_prices_status', '1');<br />    }<br />}<br />add_action('init', 'update_existing_variations_to_manual');
