Cannot import all files to database

I have lang files:

\lang
  en\
    ocadmin\
      common\
        column_left.php
      setting\
        setting.php
    auth.php
    pagination.php
    password.php
    validation.php
  zh-Hant\
    ocadmin\
      common\
        column_left.php
      setting\
        setting.php
    auth.php
    pagination.php
    password.php
    validation.php

php artisan translations:import

en language:
the root four files of language folder are in database, but none of all other files

zh-Hant:
Only "ocadmin/common/column_left" in database. The original four files auth.php... are missing, and setting/abc.php is missing.

So strange...

vendor\barryvdh\laravel-translation-manager\src\Manager.php

                if (! $vendor) { // line 96
                    $translations = \Lang::getLoader()->load($locale, $group);
                } else {
                    $translations = include $file;
                    $group = 'vendor/'.$vendorName;
                }

                if ($translations && is_array($translations)) { // line 103
                    foreach (Arr::dot($translations) as $key => $value) {
                        $importedTranslation = $this->importTranslation($key, $value, $locale, $group, $replace);
                        $counter += $importedTranslation ? 1 : 0;
                    }
                }
                // I add 3 lines. Why do I get emtpy $translations?
                else{ 
                    echo "<pre>", print_r($group, 1), "</pre>\r\n"; exit;
                }

Why do I get emtpy $translations?

I fixed.

vendor\barryvdh\laravel-translation-manager\src\Manager.php

    public function importTranslations($replace = false, $base = null, $import_group = false)
    {
        ...
                if ($subLangPath != $langPath) {
                    //$group = $subLangPath.'/'.$group;
                    $group = str_replace($langPath.'/', '', $subLangPath) . '/' . $group;
                }

langPath D:/Codes/PHP/laravel.test/httpdocs/lang/en

subLangPath D:/Codes/PHP/laravel.test/httpdocs/lang/en/lang/en/ocadmin/common

group (before $group = $subLangPath.'/'.$group;) column_left

group (after that line) D:/Codes/PHP/backgarden.chinabing.test/httpdocs/lang/en/ocadmin/common/column_left

What it need is 'ocadmin/commoncolumn_left'

So I write another line to handle it. It seems works!

For export

    public function exportTranslations($group = null, $json = false)
    {
        // $group = basename($group);
        // $basePath = $this->app['path.lang'];
