I has this same problem month ago. In my case, it is because my server doesnt fulfill this one requirement :
Passed Internationalization support
ICU 49.0 or higher is required when you want to use # placeholder in plural rules (for example, plural in Formatter::asRelativeTime()) in the yii\i18n\Formatter class. Your current ICU version is 49.1.2.
To check, just open yourapplication/requirements.php in your browser.
If your icu version status is warning, i believe that is what cause the problem. In my case, the gridview is working fine for language en, en-US, de, es, but show the same as yours for my language ms-MY.
