Name duplication after major update to 8.2.0

[Ben J.]

After updating from 1.7 to 8.2 and making a lot of changes, I am getting a lot of new customers with their complete name in the first name AND last name fields. I'm not sure where this is happening but I suspect a payment method like apple pay. I'm guessing finding where it's coming in won't help anyway. 

Is this a known issue? Is there a way to prevent this? A lot of my shipping labels print with double names before I even notice it.

Digging into the orders with double names, I have found a lot of them used ApplePay but I found an apply pay that didn't duplicate and I found Amazon pay that did duplicate the name.  

All of the orders are using Stripe payment and bypassing Prestashop checkout.

Are you using any social login plugin like Google OR Facebook login?

The social login plugin might also be the issue.

No, it's the express checkout module. I used AI to help me find the problem. 

$psCustomer->lastname = $expressParams['billingDetails']['name'];

$psCustomer->firstname = $expressParams['billingDetails']['name'];

You can clearly see the firstname and lastname are given the same name variable. 

AI gave me a fix for this but I'm hesitant to try it on a live store and don't have a test store set up.
