Pagefinder preview not showing slug and showing "% %" in title

Hi All,

I have a question. I have a menu item blueprint with a pagefinder field:
url:
label: Url
type: pagefinder
allowedTypes:
- url
- entry-xxxxx

When I go to create a new menu Item it and use the pagefinder selector it shows the page (entry-xxxxx) title as:    Canberra

And the preview:
Canberra - wiki / Wiki Article - /xyz/:fullslug/:id:

Is there something that I am missing?
