If you use Nominatim, for the location fields problem, you can fix the problem like this.

In /inc/classes/BxDolLocationFieldNominatim.php

Replace

$sRet = $oForm->getTemplate()->parseHtmlByName('location_field_plain_auto.html', $aVars);
        }
        else {
            $aFields = array(
                'lat' => array('type' => 'hidden'),
                'lng' => array('type' => 'hidden'),
                'street_number' => array('type' => 'text', 'ph' => _t('_sys_location_ph_number')),
                'street' => array('type' => 'text', 'ph' => _t('_sys_location_ph_street')),
                'city' => array('type' => 'text', 'ph' => _t('_sys_location_ph_city')),
                'state' => array('type' => 'text', 'ph' => _t('_sys_location_ph_state')),
                'zip' => array('type' => 'text', 'ph' => _t('_sys_location_ph_zip')),
                'country' => array('type' => 'select'),
            );


By

$sRet = $oForm->getTemplate()->parseHtmlByName('location_field_plain_auto.html', $aVars);
        }
        else {
            $aFields = array(
                'lat' => array('type' => 'hidden'),
                'lng' => array('type' => 'hidden'),
                'street_number' => array('type' => 'hidden', 'ph' => _t('_sys_location_ph_number')),
                'street' => array('type' => 'hidden', 'ph' => _t('_sys_location_ph_street')),
                'city' => array('type' => 'text', 'ph' => _t('_sys_location_ph_city')),
                'state' => array('type' => 'text', 'ph' => _t('_sys_location_ph_state')),
                'zip' => array('type' => 'text', 'ph' => _t('_sys_location_ph_zip')),
                'country' => array('type' => 'select'),
            );

So just put "hidden" the fields you don't want to see

But it would be nice to have a high precision/low precision option because not everyone wants to ask for the precise address.
