PHP errors

Getting flooded with there types of errors: (using latest woocommerce)

order_date was called incorrectly. Order properties should not be accessed directly.

id was called incorrectly. Order properties should not be accessed directly.

post_author was called incorrectly. Order properties should not be accessed directly.

billing_email was called incorrectly. Order properties should not be accessed directly.

order_date was called incorrectly. Order properties should not be accessed directly.

and on and on and of course the errors are very lengthy but i just posted the main line of each.

And they all end with this: wc_doing_it_wrong. This message was added in version 3.0.

Needs to be updated for Woo-commerce 3
