Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Shortcodes are usually not read by Rank Math (nor other SEO plugins) if the devs don’t add support. In your case, you could ask the plugin developer to add support for Rank Math, it will take them just some minutes and it will work perfectly with Rank Math. Here is a little guide you could send them: https://rankmath.com/kb/content-analysis-api/
About if it will create SEO issues for you; no, it doesn’t. Meanwhile you won’t get an accurate SEO score from Rank Math (due to not being able to read the shortcode), Google will read the page source code, so it will rank with no issues.
Looking forward to helping you. Thank you.
