Im too novice but I think it's a bug because the fact is too clear.

I created a custom autorig that can be seen in this post
http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=10471 [sidefx.com]

In the autorig asset created, into the preferences tab I can select any of the rig parts to make then visible/invisible. BUT in the head and neck part, the neck part doesn't disapear, only the head… even if I uncheck the Display Controls checkbox, all other controls disapear, but these 4 nodes doesn't.

Im using the Houdini 9.0.794 version
