Shipstation order status problem?

Hi,

I have a problem when the Opencart (Version 2.0.3.1) generate orders and push to Shipstation.

The connection was set up according to the Shipstation guide, and Shipstation can import orders correctly after payment, but the only problem is that it won't show up in the "Awaiting Shipment" tab like it should, rather than status like: shipped. (Isn't the status supposed to be awaiting shipment before we print the label and then turn to shipped after we print the shipping label?)

This will give me a lot of trouble because every time I have to manually search the order and print.

Can anyone help?

Thanks a lot!
