How to remove category id from url

Hello, 

So within the store application i have created a product group named plans shown below. 

I am creating an external link on the navigation menu manager so the user can go direct to the category without going to the front page of the store first.

I have gone to Advanced Configuration - Friendly Urls and edited the url. 

the url now displays as example.com/access-plans/?cat=9

How can i remove the ?car=9 from the url of the category page? 

I want the category url to be as follows: example.com/access-plans
