I have a site which is implemented for both English and Japanese. I have installed SEO Yoast and when I used "Custom Structure" for the Permanent Links then in the title of the every page in my site, it is displaying the both the English and Japanese. For example: it is showing like "<Sitename> - AboutusSbsIn7SX#2!E"
However, when I used "Default" for the Permanent links then it is only showing English when it is in English version and Japanese when it is in Japanese version for the page title.
Do you know how to fix it?
