Hello @surferking,
Thank you for your query and we are so sorry about the trouble this must have caused.
Unfortunately, it may not be possible at the moment as the Content Analysis will look for actual numbers, not the shortcode.
Please note that these tests and SEO scoring are just guidelines and one does not need to follow them religiously as Google will still be able to see the correct title with the numerical year on the frontend.
You may also disable that test if you want: https://rankmath.com/kb/disable-seo-content-tests/#number-in-title
You may refer to this guide on how to add filters to your website: https://rankmath.com/kb/wordpress-hooks-actions-filters/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
