I have a problem with the url of the SP Simple portfolio items.

I have created two categories and several products in each category.

I have managed to display each category with a different menu and everything works fine except for the ulr of the second menu item.

For example: when i go to see an item in the first category I get this url: /index.php/cat 1/item when i go to see an item in the second category I get this url: /index.php/cat 1/item

The problem is that in terms of the UR,L it is as if both articles were part of the same category and it is not like that

how can i fix it? please, help
