Not copying Yoast data

Hi. I realized that when copying an article, Yoast title and descriptions were also copied so that’s not good for seo and Facebook posts. I can’t see any checkbox to disable these fields from being copied but maybe I can use the field in settings where I can enter fields names. How can I know what are the exact names of Yoast fields not to be copied?

Thanks

BTW, I love this plugin, good job!
