Welcome to the WPML support forum. I will do my best to help you to resolve the issue.
Just make sure, have you translated the English homepage manually(from Elementor Editor) in the past?
The following template used for the pages is not translated into English and German yet.
hidden link
So please try the following steps after a site backup and make sure the issue exists or not.
1) Complete the translation of *h7 section 5* template to secondary languages
2) Open the Homepage for editing in the default language
3) Update the page after a minor edit in the contents to refresh the translation settings
4) Update the translations
5) Clear all types of caches
Thank you for the updates. Please try the following steps after a full site backup{mandatory} and let us know your feedback.
1) Please visit Pages>>All Pages
2) Switch to the English language via the Dashboard language switcher(of top header)
3) Trash the English homepage
4) Delete the English homepage from Trash
5) Retransalte the Homepage(because of Advanced Translation Editor we will have translation memory)
If the exists, please allow me to make a duplicator copy of your site using the Duplicator plugin(https://wordpress.org/plugins/duplicator/) for debugging the issue on my local server. So we can troubleshoot the bug without affecting your live site.
