Not supporting Multi Shipping

[dyuk1987]

Magento version #: 2.2.5

Edition (EE, CE, OS, etc): Open Source

Expected behavior:

The shipping fees are well calculated separately for each and every address.

Actual behavior:

The shipping fees are messed up, except for the first address selected.

Steps to reproduce:

1. Create a few shipping methods with this extension.
2. Add a few products to the cart on the store front.
3. Checkout with multiple addresses.
4. Select more than 1 shipping method created by this extension.
   
5. The shipping fees are incorrectly calculated when we proceed to the "Review Order" step.
