WooCommerce intergation - Currency not synced

we have enabled the integration for ERPNext and Woo-commerce and the orders and items sync with no issues but as our woo-commerce is multi-currency the currency of the orders are not synchronized into EPRNext properly once the sales order is auto-created. need to consider this issue and find a fix or a work-around for it.
the ERPNext version was v13 hosted on FC.
