Why isn’t my generator linking to the same place, as my menu?

There are two type of pages, one of them are the content pages, like Joomla articles, webshop pages, K2 item pages, etc.. The other pages are the Menu Manager pages, including the menu points, what you have created for your menu. You can create for example a category page, and go to your article from there, you can also create a latest articles page, so there are a lot of options to reach an article, and there is no way to know, which one you want, that is why our generators are just linking to the default simple content page.
