WooCommerce Ship to Multiple Addresses Compatibilty

We’re having a slight compatibility issue with the “WooCommerce Ship to Multiple Addresses” plugin. I am able to set multiple addresses as expected but once the addresses have been input I expect to see something like this.

Instead we just see this below.

Any help would be appreciate.
