Question Confused by notification from let's encrypt Expiry Bot

[PeterKi]

Server operating system version

Ubuntu 22.04 on strato KVM server

Plesk version and microupdate number

Plesk Obsidian Web Admin Edition Version 18.0.59 Update #2

Today, I received an email from [email protected] about a certificate expiry for my domain.
It says "Hello, Your certificate (or certificates) for the names listed below will expire in 19 days (on 2024-05-18)...."
When I check my certificate in plesk's SSL-It extension, it shows 2024-05-29, though.
Where does this discrepancy come from?

If I remember correctly this sometimes happens when a certificate has previously been renewed manually. There have been quite some 'false' expiry notification in the past, but I believe the Let's Encrypt team solved most of these a while ago.
