Bilingual Website Help

Hello everyone! I want to have my site in two languages (German and English). I’ve created both language options in the CMS collection. It work when I connected for the testimonials. I am struggling to connect the English text on the project pages. There is a project template page that is automatically created when a project is added to a CMS collection. I was able to update the info to English on the English project overview page. But when you click on one of the projects on the project overview page you are taken to the German project page. Does anyone know how I can fix that?

I also want to have the navigation in English for the English version. Can anyone please let me know how to edit the symbol without editing the German one…

Thank you very much!
