Sugarcrm - 管理模块中未显示自定义字段标签文本

I have been developing a module for Sugarcrm and the issue is that while the fields themsleves show up in the config panel they only show the label variable names and not the actual text.

$mod_strings = array(
'LBL_MODULE_MANAGEMENT_TITLE' => 'Company text', //rest of code omitted

So in my case "LBL_MODULE_MANAGEMENT_TITLE" is showing up instead of "Company text". What could possibly be the problem?

Maybe you have a concurrent languagefile in custom/modules/ModuleX/language/en_us.lang.php.

Please specify the path where your languagefile is located.
