Hello @Bonnie,
1. We suggest that you try to localize the strings in the XStore theme and Core plugin by navigating to WPML > Theme and plugins localization > Strings in the themes and Strings in the plugins and using the String Translation feature. If this does not resolve the issue, please contact the support team of the WPML plugin.
We created Multiple headers option and added a language selector to the conditions to allow users to translate headers content to other languages.
Some header elements do not support WPML string translator, so you need to create separate headers for different languages, and write correct texts in the settings of header elements.
2. Please try to contact WPML support on this issue, They will solve it for you.
Best Regards,
8Theme’s Team
