Before this thread gets assigned to my colleague, I'd like to offer some initial guidance or potential solutions.
If the option shown in hidden link">this screenshot is enabled in "WPML > Settings > Media Translation", the image metadata (Title, Description, Alt Information, Caption) will be available in the editor for translation. Could you please check and confirm if this option is enabled?
If you continue to experience the issue, please share the workaround you have used. This will help us check if it has any impact on the problem you are facing.
Looking forward to your response and we are always here to help.
The workaround is to do a search query, such as "Lanau" in the search box. Then, the missing Yoast keyphrases show up for translation. But, it is also hiding lots of content on the page, particularly the image texts (Alt, Title, Description).
