Notification Bar covers up admin bar AND fixed header

Great plugin, first of all. LOVE it!

I recently added a fixed header to my site which caused some compatibility errors with my admin bar, but now after resolving that and adding this plugin I noticed that this plugin covers over both the admin bar and the fixed header. Is there any way to make sure they both respond to the presence of the notification bar, rather than have them hidden underneath?

Many thanks for your help!
