Pitch rate missing from plot in Tuning for Airplane mode PX4

Trying to tune an airplane controller using QGround with PX4. In the Tuning page the live data for the pitch rate is missing. Is this a configuration problem on my end? Thank you for your help.

For reference, I am using QGC 4.0.0. It seems a lot of the real-time chart code is removed from the newer QGC code. I am attempting to debug and compile QGC 4.0.0. Getting QT configured is a bit of a bear. I am still not sure if this is a bug or a configuration problem on my end. Always learning. Thank you in advance for your help.
