InventoryLab uses the Selling Partner API (the approved tool of communication for 3rd parties with Amazon) to gather the fee information provided to you initially while researching or listing. Fee differences are more likely if your item is in a sub-category.

Once this is done, the Profit Status will show as Reconciled:
