Please note that if issuance is successful it does NOT help to issue MORE certificates, as clearly the problem was not with issuance.
So you re-running whatever you did to get all those duplicate certificates is probably not the answer here, even though we would like to see an output of certbot.
However, perhaps you can share the first log file of today from the directory /var/log/letsencrypt/, which should be the most informative probably.
Also note that your website currently is serving one of the renewed certificates, but only the www subdomain. So in many browsers that won't work if the hostname in the address bar is the non-www version of your domain. My advice is to include both hostnames in a single certificate to make your life easier, which unfortunately means you'd need to issue another new certificate, but now for a good reason.
