Licensed plugins data

“Note:- The Plugin which are showing NULL that are not found on wordpress org as they may be Custom Plugin or licenced Plugin so please check it with the Author or from the website you have buyed, that is there lastest version avaibale for the plugin.”

Would it be possible that you check in the readme.txt for the plugin and/or in the main .php file to get some of the data instead of showing null?

Also, the free plugin Rank Math SEO is showing null, but they are on https://wordpress.org/plugins/seo-by-rank-math/
