Language switching not working

The translated text of “Your Referral URL:” to Chinese isn’t switching when I select the China flag. I’m using qTranslate-X plugin for language switching, while using Loco Translate plugin for translation and minor POT amendments.

There was a small mistake in your POT file, where I spotted “Your Referal URL:”. It was missing a ‘r’ (small R). Then I checked your “class-gens-raf-public.php” file in the “public” folder, and found that this string is enveloped in the translation tag.

However, I still get it to switch between English and Chinese. Is there anything amiss?

Please advise soon. Thank you.
