I have an Unreal 4.22 and the Wwise Integration 2019.1.0.6947.1305,
When i upgrade the Wwise in my Project, the feature "Spatial Audio" in an akComponent, i dragged and dropped in my scene, isn't accessible.

But when i open the WwiseAudioLab project without upgrading the Wwise in Project, i can access to those parameters.
Do i miss something ?
