Human Pose Labeling Tutorial: No rig section when selecting all assets under Models and Animations

[tleyden]

The instructions say:

Action: Select all of the assets inside the Assets/Samples/Perception//Human Pose Labeling and Randomization/Models and Animations.

But if I try that, the rig option is not there:

Workaround: if I deselect KeypointCube and LabeledAndRandomized, then the rig option does appear.

Looks like maybe KeypointCube and LabeledAndRandomized were later added and don't have a rig property?
