Header/Footer Bar only on Right side of Split Editor

I am starting to use the Split Editor feature in Scrivener. I notice that I only see the “Header/Footer Bar” on the right side, and cannot get that to appear on the left side. Is this “operator error” on my part or some type of bug. I’ve tried “moving the focus” to left editor and right editor (does nothing), clicking in the other editor, etc. What am I doing wrong?

The Header and Footer bars are controlled by the View -> Layout submenu. Make sure that you have the cursor in the side of the split editor that you want to change.
