Rigify - How to adjust the super spine? I've been trying to create rigify rig, by using the sample types.
For example the sample the spines.super_spine. 

Now I found out that we can adjust the amount of segments. (in the manual, https://archive.blender.org/wiki/index.php/Extensions:2.6/Py/Scripts/Rigging/Rigify/#Advanced_Usage) 

When in pose mode, in the bone tab, I went over to rigify type. But whenever I change one of the settings, the spine chain doesn't update or I'm missing a step. This is what i'm doing:



Can someone explain to me what I'm doing wrong or better how to properly adjust the spine, and still keep the metarig fully functioning?
The final rig is created when you press Generate Rig (in Armature tab). Changing the options has no obvious effect until you generate the rig. Also I am not sure which version of blender you're using but it seems like you're using the legacy super spine. There is a newer one that separates head/spine/tail in different rig types.
