pricingSummary doesn't return valid totals

I am seeing a few random orders in a getOrders response that don't have totals that match with the Ebay portal or within it's own json object.

For example, I have the following pricingSummary:

"pricingSummary": {
    "priceSubtotal": {
      "value": "39.99",
      "currency": "USD"
    },
    "deliveryCost": {
      "value": "0.0",
      "currency": "USD"
    },
    "total": {
      "value": "46.98",
      "currency": "USD"
    }
}

However, one of the line items (and Ebay seller portal) displays $6.99 for shipping but the pricingSummary states $0 as you can see above. Here is the lineItem with the $6.99 shipping:

"lineItems": [
    {

      "lineItemId": "10031539271610",
      "legacyItemId": "183457180350",
      "sku": "xxxxxx",
      "title": "Battery",
      "lineItemCost": {
        "value": "39.99",
        "currency": "USD"
      },
      "quantity": 1,
      "soldFormat": "FIXED_PRICE",
      "listingMarketplaceId": "EBAY_US",
      "purchaseMarketplaceId": "EBAY_US",
      "lineItemFulfillmentStatus": "NOT_STARTED",
      "total": {
        "value": "46.98",
        "currency": "USD"
      },
      "deliveryCost": {
        "shippingCost": {
          "value": "6.99",
          "currency": "USD"
        }
      },
      "appliedPromotions": [

      ],
      "taxes": [

      ],
      "ebayCollectAndRemitTaxes": [
        {
          "taxType": "STATE_SALES_TAX",
          "amount": {
            "value": "3.76",
            "currency": "USD"
          },
          "collectionMethod": "NET"
        }
      ],
      "properties": {
        "buyerProtection": true,
        "soldViaAdCampaign": true
      },
      "lineItemFulfillmentInstructions": {
        "minEstimatedDeliveryDate": "2020-12-08T08:00:00.000Z",
        "maxEstimatedDeliveryDate": "2020-12-08T08:00:00.000Z",
        "shipByDate": "2020-12-01T07:59:59.000Z",
        "guaranteedDelivery": false
      }
    }
  ]

Also, you'll notice the ebayCollectAndRemitTaxes contains a $3.76 charge but it's not reflected in the pricing summary either. I've been using this in production for a year without issues until last week when one of my validations flagged the error. Is pricingSummary no longer a valid source for retrieving order totals?

Here are the docs regarding the pricingSummary which states all of the totals should be available inside the object.
