I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
As of now the autocomplete only works when you add the map on the page. This is the workaround for now, you may try to hide the map using CSS if you do not want to display it. This will be fixed in future release but there is no ETA on it.
