Need Solution on location Slug

Hi just got the idea to remove all the trailing slash from all urls as i have change the permalink setting to %postname in wordpress permalink and its working fine. But i have no clue why it breaks for only location slug when selecting location from switcher as url is making fine if enter manually:

if type manually >> http://www.example.com/location/in/bangalore

if selected from location switcher >> http://www.example.com/locationin/bangalore

need a help how to fix by adding slug after “location”

Thanks
