TI-API: unexpected unitPrice when make order

as i post the json data via the order API to buy only one NE555DR

```

"lineItems": [
      {
        "customerLineItemNumber": 1,
        "tiPartNumber": "NE555DR",
        "customerPartNumber": "MY CUSTOMER PARTNUMBER",
        "customReelIndicator": false,
        "quantity": 1,
        "customerItemComments": [
          {
            "message": "SOME COMMENT GOES HERE"
          }
        ]
      },

```

the api returns ERR-TICOM-ORDER-API-0009, the detail is 

```

{
        "tiLineItemNumber": "0",
        "customerLineItemNumber": "1",
        "tiPartNumber": "NE555DR",
        "customerPartNumber": "MY CUSTOMER PARTNUMBER",
        "tiPartDescription": "Single Precision Timer",
        "partType": "IC",
        "htsCode": "",
        "coCode": "",
        "quantity": 1,
        "shippedQuantity": 0,
        "unitPrice": 93353248.69,
        "netPrice": 93353248.69,
        "dateCode": null,
        "batchCode": null,
        "status": "",

```

why the unitPrice and netPrice is so high?
