Errors after update

We recently updated Rank Math on our wordpress and previously high scores on almost all articles are now showing 40s-50s. Upon looking deeper, clicking into the errors reveals that there is incorrect evaluations. Example: Error says that keyword needs to be used in heading but they are and we haven’t changed it for over 2 years. It also says keyword saturation at 0 but CTRL+F shows the keyword used over 30 times. This is widespread among many articles.

I’ve included a screenshot of just one example of the error but many if not most of the errors are not correct. Its important to note that this specific article has been around for quite a long time with no issues.
