Well, that's interesting.
That Subject Key Identifier is for ianmanning so it is odd to see that in a folder named for your richmond domain.
But, you did get several certs for richmond recently (below). It is far more likely something is wrong with your folder structure rather than a mis-issuance of this kind (far, far, more).
Can you show output of:
sudo certbot certificates
Have you ever used a --deploy-hook with any of your certs? Perhaps one that still exists in the Certbot hook folder?
