How to install a language pack for 3 or more languages in Magento 2?

Question

I have 3 languages in my site English, Danish and Swedish.I have created i18n folder in Magento_root/app path and I have language.xml, composer.json, da_DK.csv and registration.php files inside da_DK folder inside Locale folder which is in i18n folder Magento_root/app/i18n/Locale/da_DK/.

Translation is working perfectly for Danish. Likewise I have created the same structure for Swedish, but unfortunately, it did not work for Swedish. Path for Swedish Magento_root/app/i18n/Locale/sv_SE/

Magento_root/app/i18n/Locale/sv_SE/composer.json

{
"name": "Locale/language-sv_se",
"description": "Swedish Language",
"version": "100.0.2",
"license": [
"OSL-3.0",
"AFL-3.0"
],
"require": {
"magento/framework": "100.0.*"
},
"type": "magento2-language",
"autoload": {
"files": [
"registration.php"
]
}
}

Magento_root/app/i18n/Locale/sv_SE/language.xml

<?xml version="1.0"?>
<!-- /** * Copyright © 2015 Magento. All rights reserved. * See COPYING.txt 
for license details. */ -->
<language xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/Language/package.xsd">
<code>sv_SE</code>
<vendor>locale</vendor>
<package>sv_se</package>
</language>

Magento_root/app/i18n/Locale/sv_SE/registration.php

<?php
/**
* Copyright © 2015 Magento. All rights reserved.
* See COPYING.txt for license details.
*/
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::LANGUAGE,
'locale_sv_SE',
__DIR__
);

Magento_root/app/i18n/Locale/sv_SE/sv_SE.csv

"SIGN UP","BLI MEDLEM"
"LOG IN","logga in"
"LOG OUT","LOGGA UT"

I don't know really why the same way is working for Danish and not for Swedish. Can anyone please help me out here?

My folder structure is in the above screenshot, I don't know what I did wrong, Can anyone please help me out here?

After lots of search I have found a solution for this. I have just rearranged the folder structure and it works fine. I have renamed the "Locale" folder to danish Magento_root/app/i18n/danish/da_DK/ and created a folder named swedish Magento_root/app/i18n/swedish/sv_SE/ and placed the files inside it. Now both the languages working fine. It may help someone in future. Thanks :)
