Hello

I can only siggest some ideas how to make it together, but this question shoul be reviewed by your site developer, so, this is a issue when shipping plugins calculate costs in the customer's selected currency. FOX then converts it again because it treats all prices as base currency by default.

Solution 1: Exclude shipping from conversion (recommended)

Add this code to your theme's functions.php or a custom plugin:

add_filter('woocs_exchange_value', function($value) {
    // Exclude shipping from currency conversion
    if (doing_action('woocommerce_cart_calculate_fees') || 
        doing_action('woocommerce_calculate_totals')) {
        return $value;
    }
    return $value;
}, 10, 1);

// Better approach - exclude shipping methods specifically
add_filter('woocommerce_shipping_rate_label', function($label, $method) {
    // Mark shipping as already converted
    if (!isset($method->meta_data['woocs_converted'])) {
        $method->meta_data['woocs_converted'] = true;
    }
    return $label;
}, 10, 2);

Solution 2: Configure shipping plugin

Check if your shipping email plugin has an option to return prices in the base currency (USD) instead of the selected currency. This would be the cleanest solution.

Solution 3: Use "Is multiple allowed = NO"

In FOX settings set "Is multiple allowed" to NO. This prevents FOX from converting values that are already in pesos.
