Enable ShipStation Module in OpenCart 3

I need someone to enable the ShipStation module in my otherwise working OpenCart 3 installation, and confirm it is working on the front-end. Shipstation is installed into OC 3.0.2.0 and is successfully connected to the account on the ShipStation end using the key and the verification key. However I cannot get the module to be listed as enabled. I can change it to enabled in the module settings, but it still lists as disabled in the module list and does not show on the checkout options for shipping.
