Hi there,
1. Do the widgets supply shortcodes? If not, take a look at this plugin: https://wordpress.org/plugins/widget-shortcode/
2.Are you sure this is the correct shortcode? Which plugin are you using?
3. Currently this isn’t possible, but I’ll take a look at it as I’m putting a lot of effort into the next version of Page Header.
Let me know 🙂
