Hello, @hesham,
It looks like you haven’t translated the theme, core plugin, and WooCommerce language files properly.
For the translation, you have to use the Loco translate plugin and translate the theme and core plugin files on your site as per your requirements.
Please read this article – https://xstore.helpscoutdocs.com/article/30-base-theme-translation and create a translation for the XStore theme. Make sure that translation files are placed in /wp-content/languages/themes/ folder.
About XStore Theme, XStore Core plugin translation, you need to Sync it – https://xstore.helpscoutdocs.com/article/103-translation-files-update , then find and translate new strings. Also, synchronize translation for the WooCommerce plugin.
Hope this will solve your issue.
Regards 8Themes Team.
