Why doesn't my generator link to the same place, as my menu?

There are two types 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 just link to the default simple content page. In the generators, where you can see an Itemid option, you can change that, as you can read in their documentation but where you don't, you can't, because those don't support this and from our end it cannot be done!
