Hello @bobwild
Thank you for your message.
One of the reasons could be use of Shortcodes inside the content. WordPress editor doe not render the content inside Shortcodes but Elementor does and thus the difference in the scores.
Also, you can follow the following guide to reach 100:

But please stay advised that these tests are just guidelines and one does not need to follow them religiously.
At the end of the day, the content needs to be written for the readers and not for the search engines.
Scoring higher points in Rank Math’s tests won’t guarantee higher rankings.
Hope that helps. If there’s anything else we can help you with, please let us know.
We are here to assist.
