Sticky header navigation not displaying full with.

I have a site that is using a left hand logo, and the primary navigation aligned right. Then the entire header is set to display in full width.

This all works fine, but the Sticky header that I enabled does not display full width but instead within the content container. As a result this means the logo sits above the navigation, even though there is enough space for it to all display in one line.

How can I set that the sticky header uses the same setup as the standard header and sits full width?

The site is currently in construction and password protected, which is why I can unfortunately not display the link in this public forum. If admin wants to contact me directly I can send access details. (andreas@coolplanetdesign.com.au)
