That is very strange. Maybe it is some type of browser issue. I've tried it quite a few times now on both my android cell phone and Chromebook and have not experienced any problems with the translation. Also I disabled the automatic translation feature that I have set up on the Chromebook for Chinese websites, and then manually clicked on the translation for that website. Still got the same/expected result. Not sure why that is not functioning correctly for you.
Maybe the link below will work better. It is from the Sohu search engine and the translation wording in this article is slightly different from the other article, but basically they are the same....
