Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience that might have been caused due to that.
I tested using Google Rich Result and the page is okay. Please see the screenshot in Sensitive Data.
The warnings you see are missing fields that are optional. If you need to enter them you may do so from your post > Schema > Edit. If not, it is optional and the notification is just a warning and not an error.
I hope this resolves your issue.
