Why the price of the product in Pressero shows different from the price in ShipStation?

There is only one case when the price of product in ShipStation shows different from the price in Pressero and that is if the per piece price has more than 2 decimal places. In this case the ShipStation will only take the per piece price up to two decimal places and it does not round off.
For example: -
If I am selling a product that is priced $16 for 550 pieces, the per piece price will be $0.02909, the ShipStation will consider the per piece price as $0.02 and then shows the price as $11, though the cost in Pressero is $16
