Hi guys,
I found the solution while using this plugin and Woocommerce for Japan market. The problem is the state values in Woocommerce are different from Gmap administrative_area_level_1 values
All you need is go to Woocommerce > i18n > states and update the values of states like below:
‘JP13’ => __( ‘東京都’, ‘woocommerce’ ) change to ‘Tokyo’ => __( ‘東京都’, ‘woocommerce’ )
Cheer!
