wiki articles not showing in menu options

I have used the wiki plug in on another site.
Wiki Lite
Version 1.0.8 | By S H Mohanjith (Incsub)

When I go to create a menu, all of my wiki articles are available under
<appearance> … <menu> so that I can add them to a navigation bar.

I just installed the plugin on a new site (same plugins etc…)
When I go to create a menu, NONE of my wiki articles are available under
<appearance> … <menu> only custom links, pages and categories ar.

Is there a place this needs to be activated to make the wiki articles as part of my menu ?

or is this a functional error?
