L5 config file isn't applied

[ux-engineer]

I'm getting this error even though I've set country to FI (Finland), and tried to lookup for 5 digit long postal code – in Finland all postal codes are 5 digit long...

Wrong zip length: in BR zip length is 8 not 5.

Got it working:

$z = new ZipCode;
$z->setCountry('FI');
$zip = $z->find($code);

However before using setCountry() I've had this config with L5 in config/zipcode.php so it seems this config file's country -key isn't applied.

<?php

return [

    'country' => 'FI',

    'preferred_web_service' => 'Geonames',

    'query_parameters' => [
        'geonames_username' => 'XXX',
    ]

];

Just noticed the preferred_web_service isn't applied either.
