[Plugin: Sub Pages widget] link to parant page?

Hi, there is a checkbox with this plugin that says “Hide link to parant page.”.
That would suggest that it is possible to have a link to the parent page somewhere. Has anyone got this to work? On my site the ‘parent’ shows surrounded by H2 tags, but no link is added.

Cheers!
