MemberBar Container

The MemberBar on my private member pages is over-sized, and does not respond to size adjustments in the properties panel. Does anyone know a fix for this?

Wix Studio

What are you trying to achieve:
Resizing MemberBar Container.

What have you already tried:
Tried using the Properties Panel.
Tried using the Studio Environment (layout, style, etc.).
Tried to move the Child Elements outside of the container (which causes them to get stuck in Header/Footer).
Tried Collapse (which has the negative side-effect of hiding the child elements.
