Why doesn't my banner display when I'm looking at the Dashboard or other admin pages?
There are two banners in LibGuides, because why have one when you can have two?!
If you'd like to add a banner on your Admin pages, just go to ADMIN STUFF > Look & Feel > "System-Wide" tab and look for the System Banners box. You can reuse your public pages' banner, upload another one, or show nothing at all:
