Warning from Woocommerce plugin

I’m getting this warning:

Your theme has bundled outdated copies of WooCommerce template files – if you encounter functionality issues on the frontend this could the reason. Ensure you update or remove them. See the system report for full details.

thankyou.php version 2.0.0 is out of date. The core version is 2.2.0,
orderby.php version 2.0.0 is out of date. The core version is 2.2.0,
my-address.php version 2.0.0 is out of date. The core version is 2.2.0,
my-orders.php version 2.1.0 is out of date. The core version is 2.2.0

Is there a need to fix this or can it be ignored?
