Map Integration

I have tried to create a ‘Proximity’ Facet which connects to the google maps metabox field – the LAT/LONG of the address. It doesnt seem to work, nor does it register the location coordinates in the facetwp index table in db.

here is my meta box map field

[
                'id'            => $prefix . 'map_lat_long',
                'type'          => 'map',
                'name'          => esc_html__( 'Map', 'text-domain' ),
                'address_field' => 'building_address',
                'api_key'       => '...',
                'region'        => '.us',
                'std'           => '40.7831, -73.9712,14',
            ],

The documentation states it can filter by lat/long: https://facetwp.com/documentation/facets/facet-types/proximity/

It also says “The Data Source should be a custom field containing a comma-separated latitude, longitude.”
My map field in the custom table is stored exactly like this (provided an address is selected via the meta box building_address field).

Thanks
