Whether or not a location shows up depends on what the person has put in their own profile.  If they included a location in their profile then it will show in places their profile name is displayed such as when giving kudos.  If they did not (it isn't required), nothing will be displayed.

Thank you for responding. However, I'm experiencing difficulty removing my location information from the profile -> location. Even when I leave it blank, it reverts to the previous input.    

Hello, 
@ariba, we addressed this in another post here, but also wanted to include the solution here....

To remove your location, please use the mobile app using the steps below: 

1. navigate to the 'You' tab on the bottom right
2. tap 'Profile' (your profile image) on the top left
3. then 'Edit'
4. Once you delete your location info, click save
