We are very sorry that you have faced issues using our plugin.
The most probable reason of address field error is lack of authorization of Google Map API key on Google platform. More information about Google Map API key can be found here>>
Also, please, check settings of other plugins or theme you use – if several API keys are enabled on one page, this can cause the issue as well.
As for regional field names – they are customized via WordPress filter es_property_get_fields.
Links of components of Google addresses can be customized via the filter es_global_js_variables. They can be found in the class-estatik-ini.php file here>>
In case of any questions about the plugin, feel free to contact us at any time.
