Received email notification on certificate expiring although it is not

I received an email saying that my certificate is about to expiry, however I have my certbot running and doing automatic renewal, so that should not happen. I ran commands and also checked certificate expiration date on my Chrome and it expires on 24 of august, so it should be fine, so I don’t understand why the email. This is the email anyway (just the first line, to make it short):

Your certificate (or certificates) for the names listed below will expire in 19 days (on 31 Jul 20 20:13 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.

So, can anyone tell me what is going on? Thanks!

My domain is: (and some others, see below)

I ran this command: certbot certificates

It produced this output:

Found the following certs:
Certificate Name:
Expiry Date: 2020-08-24 11:54:41+00:00 (VALID: 40 days)
Certificate Path: /etc/letsencrypt/live/
Private Key Path: /etc/letsencrypt/live/

The operating system my web server runs on is (include version): Ubuntu 20.04

I can login to a root shell on my machine (yes or no, or I don’t know): yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.40.0

is your certificate that expires - 2020-07-31.

OK, I understand that only one of the domains expires early, but let me ask differently: why doesn’t certbot take care of that? I have registered all of the domains with certbot, it should detect which expire when and update accordingly, right?
