WooCommerce integration not working with existing orders

If I edit an existing order in the backend of WooCommerce which has the date accepted already stored in postmeta with the meta_key = ‘_wpgdprc’ and a date in the past, this date is not shown – instead the current date is always displayed.

This is also the case when listing orders in WooCommerce – the original accepted date is ignored and the current date is displayed against all of the orders.
