Hello,
I checked with the default theme and see the same order https://gyazo.com/be9b2397ecd2cfffbd3bf4c1dd17eeed
Our theme is not the reason of the issue. Try to disable third-party plugins and check after that. If it does not help then contact WooCommerce plugin support. We can do nothing if the order does not work even with the default theme, unfortunately.
Regards
