Remove duplicated location in drop down of location providers

I currently have 1 service provider, 3 locations, and 11 services. I have linked each service to one of the locations, and all services linked to the one service provider.

I am using the Make an Appointment page that is automatically created, with the added shortcode of [app_service_locations].

I aim to use the location service to filter out the services provided at the location. I also expect the drop down of the available location to only appear once. However, as each service is linked to a location an additional instance of that location is added to the drop down list

How is this resolved so the locations are only appearing once.
