Not seeing Actuators tab in QGC with Pymavlink

If I use pymavlink to connect my drone to QGC, I do not see the Actuators tab. Instead, I see the old Motors tab.

However, if I use mavlink-router to connect my drone to QGC, then I do see the Actuators tab.

Any ideas? The pymavlink script is simply forwarding all messages between the drone and QGC.
