Sendle & Delivery Customization API

We have an unusual report, and we’re wondering if this is a bug or intentional behavior.

Our client from Australia is using the built-in Sendle integration to display shipping methods in Checkout.

In Checkout, they see a shipping method called Sendle Domestic, and they would like to change it to Standard Delivery.

They’re trying to do this using our app and the action to rename the method, but it’s not working as expected. Here’s the input from the delivery customization logs:

"deliveryOptions": [
  {
    "handle": "f09ce6539929a770d80f6fa7a167a233-731abfc60131052ec0153d081d2a0120",
    "title": "Domestic",
    "cost": {
      "amount": "8.59",
      "currencyCode": "AUD"
    }
  }
]

When we perform the rename action from Domestic to Delivery, the result in Checkout is Sendle Delivery:

{
  "operations": [
    {
      "rename": {
        "deliveryOptionHandle": "f09ce6539929a770d80f6fa7a167a233-731abfc60131052ec0153d081d2a0120",
        "title": "Delivery"
      }
    }
  ]
}

The name of the shipping method we receive in the input is different from the one we see in Checkout.

Is this a bug, or is it intentional behavior? Why is the full shipping method name not passed in the input, only a part of it? And why is only part of the name being changed?
