Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
The UX Builder uses a custom implementation of the custom fields to add content to the page like images, internal links, and Rank Math is not able to fetch the them from those fields to analyze.
The way to achieve this integration would be for the team of Flatsome/UX Builder to implement our Content Analysis API: https://rankmath.com/kb/content-analysis-api/
You can contact the developers of the theme and show them the link above.
Many known companies have already added the compatibility, as it takes a few hours:

https://rankmath.com/compatibility/elementor/
https://rankmath.com/compatibility/themify-builder/
https://rankmath.com/compatibility/page-builder-framework/
https://rankmath.com/compatibility/flothemes/
However, please note that these tests are only there for your reference to help you in optimizing your pages/post content. If you feel any of them doesn’t apply to your page or you have already done, please feel free to ignore them as search engines test the live version of your site.
I hope that helps.
Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
Thank you for the quick reply!
