Menu Link To Category Different URL When Compared To Category Module URL

I'm hoping to build a menu that will display the category structure in EasyDiscuss to have better control of how the sub-category/child items display, vs the EasyDiscuss module showing all categories and sub categories. The issue I'm running into is the URL output difference between the category module vs, the menu module (see attached images).

The URL output (which I'd like to keep) when clicking "Category A" in the category module shows as:

/discussions/categories/listings/category-a

The URL output when click the menu link that points to Category A using the Single Category option when building the menu with the EasyDiscuss options shows as:

/category-a

I have the SEO set to use the menu itemID in EasyDiscuss's settings, so I'm not sure if I'm missing another setting somewhere else.

Thanks.

EDIT - I forgot to include the site details ... updated now.
