System is changing ship dates

The Nitrosell system is changing my ship dates when the order is tendered in. How do I turn this feature off as it is dramatically affecting my seller metrics on Amazon? This is causing me to be removed from the front page and no more Buy Box. I have a 84% late shipment rate in the last 30 days thanks to the Nitrosell system.
