[uiXpress] Custom Items not showing up in Admin Bar

I am using a snippet for faster navigation through posts, templates, etc. This snippets creates items in the Admin Bar where you can klick thorugh. In the dashboar using uiXpress they don’t show up, when I am in the builder and see the classic admin bar, they show up.
