Order Tracking information not getting updated

I am uploading the CSV file with the Order ID, Item ID, Tracking ID and Slug

Order ID: Same as Woocommerce Order ID
Item ID: Blank
Tracking ID: Courier tracking number
Slug: delhivery

I have set the email to be sent, and the order to be marked as Completed upon import.

The file is getting uploaded but the tracking number is not getting updated to the order, and the order status is not changing to Completed
