Sometimes GTranslate Pro stops translating new content to not exceed the limits set by Google and it will queue the translations for the next time. During that period it will show the original version instead without "%". If you want to not wait and translate it forcibly you can add ?force_translation=1 in the end of the current URL.
I've checked your website. It doesn't seem that you have installed the plugin correctly. I'm getting 404 error page. Here is the documentationhttps://gtranslate.io/docs/57-gtranslat ... ion#plugin
