1. If the page you sent is a post archive (in other words, an archive page that is automatically displayed without you having to set it), then unfortunately you can’t set its Title Bar.
2. If it’s a ‘Posts’ page you set (using the ‘Posts’ tab) then the Advanced Options > Title Bar / Breadcrumbs should do the job. If this is what you’re referring to then send us access details to a temporary user so we could check this out.
