The language plugin is called incorrectly. I need the home page to be the same as the shop page. The language plugin at the top can switch multiple languages. Now the home page only displays one language. Please tell me how to modify it to be consistent?
I hope you can help me to solve my questions.Thank you
Please make sure that the home page is translated and that the translations are published (not a draft or accidentally in the trash).
So, try the following:
• Ensure the Shop page is fully translated and published in every language. 
• Go to Settings → Reading; on each language set that language’s Home page as the static front page. 
• Clear all page-caching plugins/CDN caches and retest in a private window. 
Best Regards,
