How many times did you create another GPS port in your configuration? That includes re-running the configuration wizard and telling it to create another GPS connection.

Go to the menu choice File->Configuration->Expert-mode, then select the Ports tab. Each line in the displayed table corresponds to adding another port to your configuration. If a port is closed due to some error (e.g., unplugging a USB GPS puck), you should fix the error for the existing port. Don't just create another port.

Since you have way too many, select one of the extra lines that does NOT correspond to your present GPS hookup and click the Delete button to remove that excess port from your configuration. Repeat until only ports corresponding to your actual hardware, network, or software hookups (such as an AGWPE port to a Direwolf instance) remains.
