Thank you for contacting Telerik Support.
As far as I understand, you created two pages - one in English and one in Spanish with a language selector. Both pages are synced. Normally such pages display content only in their own language. However, if you, for example, have a content block in the first page and the content in it is in English, then the Spanish page would also display the English content, simply because the content block exists on both pages and doesn't have different translations. Could this be what's happening with your pages?
As for the missing content, please verify that the content items you're referring to have translations in both English and Spanish. Otherwise, if you have, for example, news items in English, but none of them has a Spanish translation, the default behavior would be to see the news widget only on the English page. Is it possible that this is why you think your content is missing? Below you will find attached a video, where I've created two translations of a page and synchronized them. Please verify that you made the same configurations when you created your pages. Also, I would like to ask you to send us a video, which describes the issue you''ve encountered, so that we would be able to reproduce it.
Looking forward to your reply.
All the best,
the Telerik team
