Is this warning normal?

Hi,
If I make a revision to an existing piece and then hit “publish”, the URL’s don’t change and everything seems to look good but – this message comes up: https://www.dropbox.com/s/m7xh835ry0oviqi/Screenshot%202019-11-15%2011.57.59.png?dl=0

Is that a false reading from Yoast, so to speak?

Thanks
