Order delivery date not showing

For some reason, when I am on checkout page, there is no option for order delivery date.

Plugin is installed, latest version and is active. Cleared caches, cookies, even tried different browser.

I think, it started after upgrading WP core and Woo to the latest versions, but this may be a coincidence.

You will need to add a product first. Here is a link to the product you can use:

Any ideas?
