Not able to display article list for a Category

Hi support,
I have installed the JUX Mega Menu extension in replacement of a free Menu I was using.
Unfortunately, I can see it does not work in the same way. More in detail, my sub-menu items are supposed to show the article list (Articles » Category List).
The problem is that, the link to each sub-menu item is not the sub-menu alias as I would expect. The link created is the category alias.
So, for example if I have Menu "basic" and submenu "option one" with alias "option1", it does not link to the "domain/basic/option1" but it uses the category alias (which is different from the submenu alias in my case).
As a result, I don't have anymore the Category List but a messy list of articles in Blog format for that Category.
Is there a way to force using the Menu and sub-Menu alias instead ?
Thanks
Francesco

Thanks for your reply. At the moment, unfortunately, I'm not authorized at the moment to share the site's backend credentials , however I wonder if it's possible to override in any way the link created for a submenu? I'd like to force using the Menu alias......
otherwise I see no option but creating a redirect in the htaccess file.....

Hi! I've sent you by email the snapshot showing more in detail the issue,
Thanks
Francesco
