Static pages not using friendly URLs in All in One SEO Plugin

Hello,

I am using Osclass with All in One SEO Plugin and enabled permalinks. 
Static pages work fine in Osclass itself, but when I create/edit pages through the All in One SEO Plugin, the URLs generated are like:

http://localhost/index.php?page=page&id=XX

Instead of:

http://localhost/slug

Permalinks are enabled and .htaccess is working for other parts (e.g., listings and categories).

Is there a setting in All in One SEO Plugin to force the use of {PAGE_SLUG} for static pages? 
Or any fix/patch to make this plugin respect friendly URLs for static pages?

Thank you!

I am sorry, but how do you create static page via all in one seo plugin?
