Problem:
The client is experiencing an issue where wpseo_titles are being overwritten in the secondary language when using WPML with the Yoast SEO plugin. This occurs after changes are made in the Yoast settings and the frontend is visited in a secondary language.
Solution:
1. Verify if the wpseo_titles custom field is set to be translatable by following the steps in this guide: Translating Custom Fields.
2. If the field is translatable, check for any triggers in the default language that might be overwriting the translation.
3. You can also try translating the wpseo_title value via String Translation. This might require locating it first within the admin texts section as described here: Finding Strings that Don't Appear on the String Translation Page.
4. If translating the value does not resolve the issue, it is likely a compatibility issue between WPML and Yoast SEO, not directly caused by WPML.
