Open Street Map not updating the address field

Hi there!

I apologize if this is a silly question but I'm a bit confused about the correct way the Open Street Map field should work.

I have a meta field with the OSM and a standard text input that is attached to the address_field:

array(
          'id' => EXR::$prefix . 'location_address',
          'name' => esc_html__('Location Address', EXR::$text_domain),
          'tab' => 'location',
          'type' => 'text'
        ),
        array(
          'id' => EXR::$prefix . 'location',
          'name' => esc_html__('Map Location', EXR::$text_domain),
          'tab' => 'location',
          'type' => 'osm',
          'std' => '43.263623, 6.644852,15',
          'address_field' => EXR::$prefix . 'address'
        ),

When I start typing the address in the text input and choose/select one, the map gets updated properly. However, when I move the map pin around, the text input does NOT get updated at all. Is this is a known bug? Or an expected behavior?

In addition, the "Find address" button below the map is NOT displayed at all. No JS conflicts/errors at all.

Thanks!
